And watch your exposure. Start with small trades so you can be comfortable with that amount of risk before moving up. High leverage means your position value changes much quicker so you have to be careful about how big that position is.
Another simple but important tip to remember is to either stop or drastically reduce your position size if you experience a big loss. Your first big loss will be a bit of a shock, and it might come tomorrow, or it might come a few years later. That shock will impact your ability to make rational decisions, so check yourself before attempting to "win it back" with another big trade. Chances are that pattern of thinking will ruin you.
That also brings up taking losses. Small losses are good, and some professional traders make up to 80% of their trades as losses, but make 10x more money with their winning positions. So don't be afraid to close out if it's not the right one.
