Soooo... (10 x 1) - (10 x 1) is exactly correct: PER CONTRACT is Net zero at days end. The other way, PER TRADE feels better though. Tough!
NET P&L / Total number of contracts (not sides) traded is completely misleading if you are doing different size trades and/or adds in a non-martingale fashion when determining PER CONTRACT. JMO
Agreed. I don't add/scale a lot, so I'm thinking it could possibly work as an approximation. I might track both.
As you track points per contract yourself, it seems - how do you go about it?
As for other platforms, Sierra trade aggregation or not, is as option through it's scale-in/scale-out settings and other trade treatment settings.
Nice. The reasons for leaving NT in favour of Sierra are growing, but I'm 'married' to NT, so won't do it anytime soon.
And all part of the "difficulty" in finding an acceptable alternative platform.
