Yeah, thanks. I hope it will happen, after 12 years. I hope the potential will materialize.
 
How greed affects your risk/reward aiming

I have run out of things to complain about. I've said enough about my dad and my colleagues. I would do myself and everyone a favor if I stopped wasting time writing and saying the same things over and over again. Maybe I am ready for a change. For a change in habits. At least that.

What I've always wanted is a more radical change: to quit my job. Every morning I sit at my desk and whisper "quanto manca?". How long more? How much more time? How much more of this? I know that's the major source of my frustration. But that's exactly what's kept it from happening: wanting it too much. Aside from my gambling that's what hurt my trading: a desire to make money quickly so to quit my job as soon as possible. I caused the opposite to happen because the quicker I wanted to make it, the quicker I lost it.

That strong drive to make money blinded me into making improbable trades. The more I wanted to quit my job the more I was neglecting the unprofitability of my choices. By the way, I was just googling "blinded into making" to see if I could use that expression, and I found this other trader who describes the same concept here: "Well, on hindsight, the read on the second trade was full of wishful thinking.... After a successful trade, the euphoria and greed blinded me into making a trade that was not supported by any evidence".

That's why they're all talking about discipline - and since everyone is talking about it, as usual I assumed it was bull****. Yet discipline is what I need, to prevent myself from letting my desire to quit my job blind me so much that I'll make unprofitable choices. If trading were like the lottery, and I all I needed was to win once, then I could try all improbable trades I want. But since I need thousands of trades before I can quit my job, choosing improbable trades will not work.

It's like when you're playing a video game and you're wasting ammunitions - you aren't even trying to aim. Or when you're playing risk and you keep on rolling the dice until you're down to one army even though you know the odds are against you. If I don't want to call it "discipline", because that's what everyone calls it, then let's say that I better calm down, because the more I rush to conquer the world, the faster I will be wiped out from the map. This is all about being a sniper and aiming and not about shooting away and firing at will. As far as my discretionary trading, every bullet costs me 250 dollars, and so, with 5000 of capital left, since margin is 2500 dollars, I have ten more bullets to go. Each time I hit the target, I gain one bullet. Each time I miss, I lose one bullet.

travis ur right man,about leaving this job and free,i have the same feeling,u ahve this longing to be away from all this boring and stressful stuff and be away on some sunny beach and enjoying nature but what can one do.time is not with us.one is constraint somehow in so many chains.even one wants it u cant break it.but on the other hand think of it this way what is the purpose of it all,suppose one has all the freedom and u can do whatever u feel like then the problem arises, how one going to structure his/her time.u can't be doing this boring stuff called trading,meditation,enjoying nature all ur life.some how life get u and forced u to in this world of comparision,life and death,day and night,black and white,light and darkness...and so on.there is no way one can comes out of it and be urself.there is too much noise in this world.but again probably one need it so that one can keep sane oneself...hmmm
 
Hmmm... ok, so we need to keep the bad, as a term of comparison, to appreciate what's good. Yes, it makes sense. But then we could take it further and say that instead of eating a cake, we could starve ourselves to death, and just eat a piece of bread, and it would taste better than that cake. Or we could deprive ourselves of things, in order to enjoy our regular life. I don't know. Yes, we could. It doesn't feel natural at all though. What feels natural is to get better and better and more and more. If I could do what you're talking about then I could stop trading, because my job gives me enough to live, and if I am unhappy I can always resort to starving myself to death, in order to appreciate bread and water again. And if I am unhappy with my job, I could go work in a coal mine for one day, or similar. Yeah, I guess I could manipulate myself to be happy in any situation. But I would be manipulating myself... it reminds me of that movie, Matrix.

 
Mentally preparing for tomorrow...

Preparing for tomorrow, renewing my promises and resolves, here's the plan I will have to follow from now on:
1) Automated: safe money management parameters, and no interfering with anything.
2) Discretionary: just one daily trade allowed, and it has to follow all rules in system.

----

If I'll follow such rules, realistically, I hope to make about 1000 per week: 500 from discretionary and 500 from automated. It's going to take me one month to get back to 10k. Then, with 10k, following the same rules (but doubling the contracts on discretionary, and with more automated systems trading), I should be able to increase my capital by 2000 per week. And so on. Basically, instead of aiming at 100% per week, I am aiming at 100% per month, and this way, like the sniper I should be, I won't waste my ammunitions: one shot per day. Realistically, I am planning to make 100% a month. Same old dream/plan.

If it doesn't happen, I'll come here to report it, as usual. If it happens, once I'll get to 20k, I might stop posting because it means I have finally learned to be profitable, and it's useless to show off.

I must be like a sniper...

Continuing the trader/sniper analogy...

Continuing the trader/sniper analogy. My gun is my bracket order. We could say that part of my gun - my "sight" - are also the moving averages and the pivots I use. So I have this "+/- 20 ticks bracket order rifle", and I shouldn't be changing it, because it'll take me a while to get used to it and because, whether good or bad, with practice I can learn to hit targets with it. But each time I'll miss, I'll incur a cost of 250 dollars per bullet. Each time I'll miss the future direction of price, the market will wound me by destroying 250/5000=5% of my account.

When I wasn't using a stoploss, I was engaging in a duel/showdown with the market, where I either won or I was killed and my capital wiped out. But when I won, I would only take 250 dollars out of the market, and therefore I'd have to fight more duels, each time risking my life. That's why I ended up dying 30 times, regardless of how good I was at shooting.

So risk/reward could be compared to how much you'll be hurt if you miss vs how much you'll hurt your opponent if you hit. But alone it doesn't mean much: you need to know how good you are at aiming. So it's risk/reward plus percentage of wins. Yeah, because if you have a bracket order of -1 and +10, your risk is -1 and your reward is +10, which is awesome, but if you end up losing 9 times out of 10, with commissions, it's still not convenient. So this relentless talking about risk/reward is actually crap, isn't it.

Re: Continuing the trader/sniper analogy...

So this relentless talking about risk/reward is actually crap, isn't it.

Well no it isn't. Although it is crap when it is considered in isolation which unfortunately seems to be often done by many (which is perhaps what your'e saying?) What most people don't seem to understand is that reward:risk is attached to the hip with win/loss ratio, as you yourself in fact just pointed out. Taking the 2 together as you should, then reward:risk becomes very important and a useful tool to evaluate the overall quality/profitablity of your system.

To reiterate/explain: It's meaningless to talk about risk:reward ratio in isolation. It can only be meaningful if you also always combine it with the win:loss ratio expected for that risk:reward ratio (and vice-versa), because only if you have both values, can calculate your APPT which stands for "Average Profitability Per Trade" (also known as "Expectancy" as used and described by Van K. Tharp in his book.)

It is obvious that unless you are on average net profitable your account balance will decline over time (even if you have the occassional upswings). We're talking averages here. And that if you *are* on average net profitable, your account balance will increase over time (even if you have occassional drawdowns which are not too severe to overcome).

The formula is (hopefully simple!):

APPT = (Average Winning trades % x Average Win size) - (Average Losing trades % x Average Loss size)

For example, let's say that on average you profit on 2 out of 10 trades (so you lose on 8). This means you have a 20% (0.2) win rate and a 80% (0.8) loss rate. This means your win:loss rate is 1:4. Let's also say that on average, you win $1200 when you win and you lose $300 when you lose. This means your reward:risk rate = 1200:300 = 4:1. You might think that with such a high reward:risk rate you should be profitable. However let's see what the sum says:

APPT = (0.2 x $1200) – (0.8 x $300)
= 240 - 240
= $0 on average

So you're only net break even, on average! Despite having a 4:1 reward:risk ratio! So, looking at reward:risk without taking into account win:loss ratio/probability is... meaningless!

Let's now say you you profit on 8 out of 10 trades on average ( so you lose on only 2 out of ten.) This means you win on 80% of your trades (0.8) and lose on 20% of your trades (0.2) and your win:loss ratio is 80:20 = 8:2 = 4:1, which one might think is obviously quite high and on the face of it very good. One might think that you have to make money with such a good win:loss rate. (Such a high rate plays into our "wanting to be right bias" of course...)

Suppose further your average win size is $200 while your average loss size is $1000. This means your reward:risk ratio is $200:$1000 so is 1:5. Here some alarm bells should be ringing as that's a very low reward:risk ratio, but the jury's out until the sum is done. The APPT then is:

APPT = (0.8 x $200) – (0.2 x $1000)
= 160 - 200
= -$40 on average

So despite the very good win:loss rate (4:1 or 80% of trades won) you will still be a net loser with a system that trades like this.

But notice, if you can reduce your average loss size to say $500, the sum becomes:

APPT = (0.8 x $200) – (0.2 x $500)
= 160 - 100
= $60 on average per trade

Which is net profitable, despite the fact that the reward:risk ratio is still relatively low at $200:$500 = 2:5 = 1:2.5 = 0.4:1. Which again shows that reward:risk is meaningless without win:loss.

Let's finally do an example where your win:loss rate is 1:2. This means 1/3 of trades are won and 2/3 of trades are lost. Suppose further your average win size is $1500 and your average loss is $500, which makes your reward:risk ratio 1500:500 = 3:1. Then the sum becomes

APPT = (0.333 * $1500) - (0.666 * $500)
= $500 - $333.33
= $166.67 on average

So a system with a relatively modest win:loss rate which only wins on 1/3 of trades, but has a decent reward:risk ratio of 3:1 is net profitable to the tune of $166.67 per trade. As an aside, I'll finally just observe that the net profitability (per trade) of the system is roughly one tenth of the average win size of your winning trades. It would be wildly unrealistic to estimate where you'll be profit wise based on the average size of your winning trades ($1500) and instead should use the more modest net average profitability size which in this example is $166.67. Just something to think about.

What all this hopefully illustrates is that reward:risk and win:loss are equally important when evaluating your trading system's quality. It is meaningless to look at only reward:risk (assuming win:loss will be ok by magic) or only win:loss (assuming reward:risk will ok by magic).

I'll finally emphasise that what further complicates matters is that these 2 measures/variables are in fact interrelated, and not independent variables in a trading system. It's like a complicated machine with 2 dials on, one for win:loss rate, and one for reward:risk rate. One might think you can modify your system to try and improve one of them without affecting the other, but in practice it usually doesn't work like this. Typically you'll find that when you start adjusting your system to increase the win:loss rate (for example), you'll find it in turn affects the reward:risk rate negatively and vice-versa. So the challenge in good trading system development is to tune/design/tweak your system so it's net profitable overall, e.g. get to a point where the 2 variables namely win:loss and reward:risk ratio's gives you a net profitable system, despite these 2 variables being semi-dependent. (As an aside, this is why I enquired in a previous post whether you've calculated the expectancy of your systems.)

For reference, I looked at this page while constructing this post.

Apologies if you already know all this. Good luck for your trading week.

Edit:
At the risk of stating what might be obvious, what I've not said anything about is how to calculate the APPT for your trading systems. Well you need to basically calculate the following values:
1.) Average Winning trades %
2.) Average Losing trades %
3.) Average Win size
4.) Average Loss size

So for 1.) pull all your trades, count the number of winning trades, and work out the % they make up of the total. For 2.) The difference between that and 100% is obviously the % losing trades (but obviously you can just count the number of losing trades again if you like, and work out the % they make of the total.)

Next for 3.) sum up all the winning trade values only and calculate the average value of them all. Next for 4.) similarly sum up the average losing trades and calculate the average. Finally substitute the found values into the formula as was done above.

As an aside, you may also want to look at the maximum lost trade size, since if this is very much bigger than the average loss size then the resultant APPT/expectancy value may in fact be a bit optimistic in practice. (Van K. Tharp actually uses, if I remember correctly, the maximum loss size for no.4, rather than the average loss size, since that is obviously more conservative as it's "worse case" (and has the effect of forcing one to be strict about stop losses...) But don't quote me on that -- I'll have to go look that up sometime and get back to you to be sure I'm not misquoting/representing him.

Anyway, I hope that's helpful, if not then just ignore it! :)

Just a quick reply, and later I'll read your formulas in detail (it'll take me a while). Thanks for taking the time to clarify, with formulas and examples, what I was stating: that talking about risk/reward (by itself) is crap. Saying "always know your risk/reward" is like saying "always know that 1 = 2", because you're omitting "+ 1".
 
Today I came to work, even though late, and even though I didn't feel like coming at all. It's because I decided to not get fired - after not showing up on Thursday and Friday.

I don't understand why the boss has kept on loading me with work, when everyone else has been taking long coffee breaks and having a good time. Maybe because, as my father told me, it's normal that those who work, are given work, and the others, who don't want to work, are simply ignored.

I was happy that my office and my boss relied on me so much. But then, as time went by, the boss kept assigning me increasing amounts of work, without allowing me to skip some almost useless tasks that doubled the time it took me. So, while increasing quantity of work, he actually asked me also to increase quality. And at the same time, he left the slackers alone. Well, he did get them to be reprimanded by Human Resources but he didn't succeed in making them work.

So, little by little, he transferred all the work from the slackers to me and another lady and kept demanding higher quantity and quality all along. Until Wednesday, when the situation became unbearable, because it suddenly was clear to me that I couldn't go any further, and that, even at that pace, I would have been overwhelmed by work - and yet he still was increasing his demands as usual.

So I said to him: look, I don't know what to do anymore. I can't keep up any more. And, as usual, he said: "tell me what you have to do", and then he proceeded to show me how I could fit everything into my schedule. His faulty reasoning is always the same: if you can produce one statistical table in 15 minutes, you can produce four of them in one hour, and 40 tables in one day of work. Another thing he does is this: can you do this table for me? Oh, nice, now do it every week. Ok, now add these columns to it (and add them every week). Ok, now do this other table. Good, do it every month. Ok, after 3 years, four different offices are relying on me for weekly and monthly reports that they're supposed to be doing but that no one in their offices wants to learn to do. And when I say I am tired, they seem surprised: "what's the matter? It's the same table as last month". And I say "I don't even remember how I did it last month".

Until Wednesday I cared about getting everything done in time, getting all the statistics done, the registration of suspicious transactions reports, and getting in touch via phone or email with all the many portfolio managers who filed reports without the required documents. But Wednesday night I've decided: **** it, I've been telling you for months, in all possible ways, that you're overloading me, and you won't get the point. From now on, I will just fall behind, since you won't even allow me to decrease quality. I will just fall behind like everyone else, and be relaxed like everyone else. And even the last person working in this office, will start being unreliable and relaxed.

So the first thing I did, since he wore me out enough, was taking two days off, without even telling anyone whether I was sick or on vacation. Go ahead and fire me if you want. And the second thing is that now I am totally relaxed. You want to break my back? Fine - it's finally broken. Now I can't work anymore and you'll finally understand - too late - that you've passed the limit.

I am not anxious, I am not worried about not reading every email and not opening any envelope... I'll let work pile up like everyone else. The last efficient employee of your office has ceased to exist because you have exploited him beyond the limit. No more guilt. No more anxiety. No more caring about the health of my office. You didn't listen to any of my warnings, so now you can go ahead and get fired for letting your office waste away, by pushing the wrong people. You should have bothered the slackers instead of the ones who were already working.

So, wprins, I see you've gotten into the risk/reward and percentage of wins talk quite in depth. You've clarified some things to me, as far as the formula. I am glad we agree on the principle of not talking about risk/reward alone. I resented a little bit how you said that I was wrong (at the start: "Well no it isn't"), but I resisted starting one of my arguments.

I got into the comparison of the trader to the sniper (or just someone shooting), and want to take it even further. Help me out.

Let's say that how a good a sniper you are, how precise, how good at aiming is equivalent to percentage of wins: this comparison is quite clear and easy.

The shooting is risk/reward, and it all depends on your gun. How much damage you do, and how much it costs you to shoot (bullets and so on). Each bullet costs exactly as much as your stoploss. The bird you shoot down (let's forget about the sniper and just say you're a hunter) is equivalent to the target profit.

If you can don't like the details of this complicated analogy, you can slightly change them.

My point is that your rifle consists of stoploss + target profit. And there can be many different type of rifles. Which rifle do you think is best for shooting the EUR bird? And I will list some examples of rifles but you can add others that you think are better. In my opinion, with practice, one could become good at hitting targets with any rifles, as long as those rifles have the stoploss.

Rifles that I can think of:
1) bracket order of +/- 20 (takeprofit at +20 and stoploss at -20 ticks)
2) bracket order of +40 and -20
3) bracket order of +/- 10
4) trailing stop of -50 (which is also a take profit, if prices go your way)
...

Add more and give me your opinion. The rifle that I can use best is +/- 20 ticks.

(My automated trading is entirely different and it's more like fishing, with fishing nets: you drop them on a given spot at a given time, and you take them out of the water at another time. And there are no aiming skills to be developed by me).

I'm sorry for that - it was a snap response, which I should've edited out. (I did in fact clarify etc as you saw, however I should've edited that initial response out as it was a bit sharp.) My apologies again! :eek:
