Where can I incorporate the lot volume martingale logic?

If I generate an EA automatically with the MQL5 Wizard, where should I incorporate the lot/volume martingale logic?
  1. In your code.

  2. Martingale is not a strategy. It's a betting system.

    Hedging, grid trading, same as Martingale.
