dude, there s no short, long span of time to learn forex, take ur time. if i may suggest, start with price action. choose a representation of it like normal candles, bars, renko, range, etc…for example i like heikinashi candles. after that learn why price moves the way it moves, catalysts, support, resistance areas…basic stuff, but without them u can t move forward.
Ps< i said to start with price action cos many in the begining jump straight to strategy, without knowing the basics(like myself in the beggining) and that would only set u for failure.
