I usually go with 2-4x leverage, and that gives me safer liquidation price however this time I went with 10x leverage, as I thought bulls have arrived, and it's only up from here, and you see how wrong that turned out.
Take whatever lesson you want. For me, it's to stick with 2-4x leverage with which I tend to do good, don't allow greed to enter.
I would say the entire concept of leverage is very risky. While you are doing day trading, invest what you have and do not borrow money from your broker. Even though your loss is limited to the money that you are actually holding, but with leverage you are taking additional risk of liquidating your entire principle amount.
I used to day trade but I have completely stopped because I have lost a good amount of money. Leverage made my position worse. So try to stay away from leveraging money and multiplying your risk at the same time.
