I said that my remark was not targeting you (or me) personnaly as it was a generic you. I wasn't discussing if you (or me) are capable or not to estimate the target or exit, but it is largely admitted both by traders, gurus and academics that knowing the entry is much more easy that knowing the target and the reason is just statistical: entry is generated by detecting a statistical outlier, which doesn't necessitate a sophisticated model, whereas estimating a target means prediction of future and that requires a true model... which officially cannot exist because if it existed that would demonstrate that market wouldn't be efficient.
When you say "I'm not able to figure out probability", you would rather mean you cannot quantify precisely but I'm sure you have a rough idea founded on your experience that it is giving an edge or you wouldn't make the trade (I'm speaking here about a professional trader, not about a novice gambler who has no experience and who would think he has an edge whereas he's just greedy or take the trade by impulse). It is difficult, for a discretionary trader like you to quantify precisely, I know all the more so since I am in the same kind of profile, nevertheless as I am getting more and more knowledgeable I now want to get out from the discretionary style and put everything under quantitative control because I'm now sure of the edge, I'm not sure like you about the precise edge (this is my next step that requires all the long work of automating the decision process. Unlike others who are very lose on methodology notably about backtest, I am very strict as I will require that everything should be predicted mechanically because only prediction in advance can prove scientifically that the edge is real and not due to persistency of trend).

Quote from RAMOUTAR:
Harrytrader, I find your posts very intriguing (after I'm able to understand them)
I'd like to address the first paragraph of your post...
This imply to be able to determine the target or exit, that is to say to make a prediction (even if it is a prob curve it stays a prediction and the prob curve can be completely false as it is not obvious - if it was obvious ...). Also this implies that there is an implicit probability attached to it (even if you can't determine it, its existence is unescapable as its origin is your complete or partial ignorance of the outcome). If you use a stop - which is practically obligatory in futures trading or you would get killed almost surely - then this probability is not even obliged to be equal to 50% it can be much lower so that the edge can turn negative (prob * gain or loss).
Target and exit are very obvious to me. If I had a good handle on the probability of the trade's outcome, I wouldn't need a stop. I gave up on trying to predict probability years ago, but too some degree analyze the price action adn momentum indicators while I'm in the trade. The use of a stop IMHO, is obligatory in any trade. Since I'm not able to figure out probability, the price action I concern myself with rests ini the range of entry, stop and target.
I look forward to trying to get my arms around the rest of your replies on this thread. Phew!!!![]()
Thanks for the insight Harry!
