it depends on how much risk you are ready to take. with very large leverage, you can make a lot with relatively small capital but the drawback is that a few pips up or down in the wrong direction, your capital will be erased. but if you are prepared to take such a risk well you can really do it but I would not recommend it. and 1: 1000 is the worst case scenario for a trader, with 10 pips spreading it is impossible to trade successfully !! I only use up to 1: 100 even if I am very sure that trading will really get there !! allmost a leverager from 1:20, 1:50
