P&L % = the strategy’s profit or loss for the selected period, divided by the lower of:
- the margin calculated by Tradetron, and
- the suggested capital set by the strategy creator.
Why the lower number? A creator may keep spare margin as a buffer; ignoring it would make returns look smaller or larger than they are. And if the real margin turns out higher than the suggested capital, using the lower figure stops the percentage from giving a wrong impression either way. Using the lower of the two keeps the comparison conservative.
