Leverage is not so important. There are other factors like analysis-fundamental,technical,sentimental, psychological factors, discipline and a lot more. But leverage is critical.
you just have to find what suits you.
Most brokers give it upto 888 or 1000.
but most manual traders use 200,300 or 400.
while most ea account use 500.
so you must find yours.
Internet says the safe one is 20 or 50, but that is almost equal to zero risk zero profit. you have to get above it.@Fxanbu
Indicators are so deceiving, always lagging. Trend lines & Calendars are the best.
