What is the reasonable amount you encourage to start trading

[Coyster]

You are not going to get exact figures from anybody here, but in general terms, you'd want to start small as a beginner, that should be the default idea. If you go in with a lot of money, you can lose it quickly, yes you could also lose it quickly if you have been trading for a long time too, but then you are expected to have learnt risk management strategies and apply them accordingly.

Start with what you can afford to lose as you learn the ropes. If you are also going to be trading with leverage, then use small leverage. Don't let the idea of higher profits deceive you, because the market could go against you and you get liquidated.
