for me it's a good tool, for taking advantage of the resistance and support.
we all know that whenever prices hits support or resistance, it always bounced back for the first time, I took advantage of it using high leverage trading in which otherwise become meaningless trade because the bounce probably just 1-2% but with leveraged high trade, I can turn it to 100% profit. of course there's risk management.
I usually only bet using $15 as my margin and proper TP/SL, future trading is a powerful tool if you want to make quick bucks, as long as you know how to do it. it becomes problematic if you use really high leverage for long term, because market like to create wick.
