I beg to differ. Doing exactly the opposite of what you did won't make you money neither.
Example:
Suppose my strategy is going long each day on a (clearly defined unambigious) signal, with stop 5 points and target 10 points... my win rate is only 25% so I lose money (theoretically I would need a win rate of 33,33...% not deducting commissions).
So, which if the following is the "opposite"?
(1) I short on each of these signals with a stop of 10 points and a target of 5 points.
(2) I short on each of these signals with a stop of 5 points and a target of 10 points.
(3) I go long on each of these signals with a stop of 10 points and a target of 5 points.
The exact opposite is (1) in my view. Does this mean I will now all of a sudden have a 75% win rate? You have no way of knowing that. Nor does that mean this strategy will turn out to be profitable.
If you think (2) is the opposite, than what if the reason your original strategy failed was because your stop was 1 point too small, and the market reversed and rallied each time after that? Doing the exact opposite of the original strategy, will definitely not turn you into a profitable trader overnight.
I'm sure you can think of some examples for yourself... the opposite of losing might be winning. But reversing or mirroring your trades won't make you profitable.
But what is the fun if you make money, but are chained to the computer.;
My point is that I am yet to find, or find anyone who has found, any rewards in trading, let alone sufficient rewards as to fund one's chosen lifestyle, be that hugging trees on the side of a Swiss mountain or enjoying the company of naughty young women on a big boat. We all want things that cost money - my purpose isn't to stimulate discussion as to the credibility of one person's choices compared to another's, but to ascertain precisely how that money can be obtained by trading, and if, in fact, anyone on this forum has actually succeeded in doing so.
I borrowed this from another board (have advised OP and will withdraw if he is unhappy). Its a variation on an old theme but I thought it was more perceptive than others I have read.
