Spot on, peto.
There are various ways you can manage risk. In this particular set up, which is only one of about a dozen I use, an excellent method is indeed to use the "wrong" end of the previous candle as your WORST CASE STOP.
Let's say your short entry is at $43.32 and the high of the previous "falling" candle is at $43.44.
If you trade without using Micro-Analysis (level2 buy/sell pressures T&S) then you can set your stop at $43.45 a potential maximum loss of 13c.
Let's say the maximum loss you are prepared to tolerate on the trade is $100, then your position size would be 769 shares ($100 divided by 13c).
Personally I really can't be bothered with odd numbers of shares so I round the number to the nearest hundred.
If my level 2 T&S screens were to show sudden strong buying pressure and weakening selling pressure and the trades printing off reflected that, then I wouldn't wait for my worse case stop loss to be hit and would be out earlier. However that is beyond what I'm talking about in this thread and we'll stick purely to charts. This does NOT mean indicators, but READING what the market is telling you.
My attitude is that if the evidence in front of your eyes says you are losing this trade, why wait for a stop loss to be hit and produce a larger loss? I feel you are simply paying money to the market in the hope of being proved "right" in such circumstances.
Of course the situation is different if the approach involves using ATR as a stop and then maybe, just maybe, what you are seeing is intra candle noise. There are plenty of techniques which employ ATR like that.
For those who have carefully read my earlier posts on this thread, you will recognise that this end of candle stop loss exit is the same as the taking profit exit. In a down move when the high takes out the high of the previous candle; in an up move when the low takes out the low of the previous candle.
This in no way "guarantees" you have exited at the right or best time, but it does mean you can continually take profits from the market.
Remember the "right" or "best" time can only be recognised as such in retrospect. You must always act on the evidence in front of your eyes at the time, never "wish" or "hope".
There is another approach which is very useful, but has to be used in context.
After paper trading, which has its limitations as we all know, you can start trading 100 shares at a time and gradually increase your position size as you develop and proceed and meet satisfactory success targets.
You should ONLY do this in my personal opinion if it is a slow moving stock with a low ATR and you can read it on level 2 very easily. What I mean is that if the stock is liquid (plenty of trades going through) and ticks up or down slowly at 1 cent at a time you can easily exit whenever you want and control your risk very easily. A stock like DELL would be like this.
I would not use such an approach on a stock like GOOG where the price can leap around by 20c or
30c in the blink of an eye. You are not in control in such a situation, at least not in sufficient control for a financially risk averse control freak like me
I use 1 min, 3 min and 5 min candles - the method works well on all those time frames.
