On the demo account, use all the leverage, so you can feel the difference. And 8x will be enough. The percentage of confidence is placed on the total amount.

Guys, please tell me about take profit and stop loss. Let's say you buy at 100$ s with 8x leverage.
What % do you set for take profit and stop loss? If you set 5% for stop loss, it immediately stops you out on correction... what can anyone share?
