Position sizing

The performance of a trading system can vary greatly depending on the position sizing rules and or compounding of positions. Do most developers here display their equity curves on a single contract basis or compound positions as equity increases??

From what I’ve seen, it varies. Stocks systems tend to grow their positions as their available equity increases, while futures systems tend to be more fixed-sized. Haven’t looked much into forex, and not at all into options, of which there are very few systems anyway.

thanks for that
