Hedging is prohibited both within and across accounts held by the same or separate traders. Opening two opposing positions on the same asset, regardless of lot size, is the process of hedging. It's also forbidden to stack, which is when a trader keeps taking positions without doing a thorough investigation in one direction. Strategies that involve martingale are absolutely prohibited as they are regarded as a type of stacking. You may open up to three positions simultaneously from one price point. You can open more positions after the price moves away from your entry.
