Subtract exit quantity from signal quantity

This affects how big the new position on the opposite side will be when Allow side swapping is checked. If you turn this on, TradersPost will subtract the amount it just exited from your signal quantity before entering the new position on the opposite side.

Example: If you're long 5 and send a sell for 10, we'll exit your 5-long and then enter a short for the remaining 5 (instead of shorting the full 10).

When to use it:

• You want the size of your reversals to match exactly what's left after exiting your existing position.
• You scale in or out of trades, and you want the reversal size to reflect the net difference after exiting your current position.
