What is the best to avoid your capital to disapear (margin call):
To have one big account and use small margin?
or to have different account in different broker and have more margin with diversified strategy?

i think that it also depends on how you are going to do risk management.

If you have a big account and use small margin but you not set stops, trailing-stop or cut losses consecuently you could end with open positions with huge losses

on the other side if you have different small accounts with small capital and you use "proportionally" (to the capital) more margin the risk of having margin calls is higher than in the big account, so that maybe you also lose a stake of you capital in different accounts.

Also if you start implementing more risky strategies because you also put at risk a small amount of capital, this could also end in losing all your money.

It will depend on how you mange your risks.
