Horace, I'm not clear on what you mean by you wanting to find the "risk side of my exposure". I enter a trade that has minimal risk because of my calculations on the extremity of the trend, which indicates the proximity of the reversal. If the extremity has not been hit, then there is a creteria that gets met on the corrction, so in that case, find that point when the correction is completed, then get in the direction of the trend.
If you reference has to do with some of the stereotypical risk: reward ratios, then I do not trade that way. I am not concerned with risk: reward ratios. I am concerned with how many pips I have once I press "close".
If the reference was made to getting out at the end of a certain amount of losses, then that is not something I am used to. I've had one losing week in the last 3 years. 80% of my trades end up in the + column.
If I answered your question, then okay. If not then maybe you can further clarify your question.
BTW, my methodology wins no popularity contests. It also does not fit the stereotypes of my forex philosophers or books they may right, which is why I don't spend a lot of time reading their books. The only thing my methodology does is win consistently for me.
