Option to change trading statistics & Trade limit calculation

Option to change statistics from Trades to Flat-To Flat.

Currently, scaling in and out of a position counts as Indvidual trades that skews trade metrics. Would be helpful to add a feature where the calculation is based on Flat-to-Flat, accommodating for scaling in or out of a position.

• Could also add a check against child orders to determine if a position is closed.

This would also be a nice feature for the trade-limit lockout feature.
