To your last question, he should be patient really. No rush, always use stop loss and always wait for his preferred entry before taking a trade. Now tell me about this liquidation protection you talked about. How does that work??
When you are trading you need to try not to be greedy because when you are to greedy there will be some kind of consequences that it comes with because it is not as if some people don't know what stop loss is or how to use it, they just deliberately seem not to care and if they don't do leveraging they might have the chance of making more money. They don't consider the risk that it comes with high risk of liquidation, people really are very funny, you don't want to be liquidated but you don't want to also do the right thing and this is why some times I don't actually pity when most of this traders are liquidated because obviously they know what to do and they did not pay attention to it and now they are regretting, if you are a beginner you will need to have learn to be patient because we know how careless we can be sometimes, it will be better to just put all the important measures in place so that you don't get liquidated. The more you trade the better you get at it.
