Strict money management will protect your account from fast margin calls, even though you often get losses several times, but with tight money management will have many opportunities to place an order with a new analysis, even though we have a good system but if not accompanied by good money management good will meet certain circumstances that give big losses and yes if we have a little investment, we have to use small lots because big lots make us risky and we can kill quickly in the market so we can't be greedy and have extraordinary business based on our investment but if we have a large investment we can use large lots and the business makes sense because we can return the deduction at any time.
