I'm backtesting a portfolio of futures contracts and would like to set the Position size of each trade based on each trade's risk (i.e. abs(entryPrice - stopPrice)) and a percent of the current portfolio Equity value. I understand that to get the current portfolio Equity, I need to use the custom backtester. The custom backtester also gives me access to all the data I need to calculate a new PosSize except my stopPrice values.

Using AddToComposite() and Foreign() does not seem like an option because I want my individual stop values for each instrument, not a portfolio composite of all stop values. Or maybe I would have to create a separate composite for each instrument. Or do I have to resort to something like writing and reading files or developing a custom DLL to store the stopPrices between the backtester Phase 1 and the custom backtester Phase 2? Hopefully, I'm just not understanding something and there is an easier way. I would think that accessing Phase 1 backtester variables in Phase 2 would be pretty common; especially for calculating custom metrics.
