It seems the trailing stop is not the sort I'm after. I would like something that works more like the function provided by TWS; my strategy would like to set both the stop value and the trailing value, not percentages. (On SetProfitTarget there is a bool to control this.) Also, there doesn't seem to be a way to set GTC. Setting barsValid might be the way to go, but how would that be set along with hard trailing stop values?
