The way amibroker tests it(by incremental lot sizing with profit and decreasing lot size with loss)... it is 30%.

And if I keep the lot size consistent at 125000, then there is a dip from around 45000$ to 29000 $ in the profits.

Suppose i m in a position to loose around 5000$ and not cry over it then will it be appropriate to risk that much behind this strategy?

Or is there anything in the standard error or the ulcer index etc which one of you ppl with knowledge of statistics point out and call this a waste of effort?
