Note:

1. Your Target (TG) and Stop Loss (SL) are linked to your position. If you create a TG or SL for an existing position and then exit the position manually, both the TG and SL will be automatically canceled, as they are tied to your position.

2. If you add more quantity to a position where TG or SL (or both) are already set, the same TG and SL will apply to the added quantity.

3. If you exit part of a position where TG or SL is set, the remaining quantity will still have the same TG and SL applied.
