managing money well, our trading account is always maintained, especially not often having an MC or losing.
Unreasonable lot usage is the reason for our trading account to experience MC, this is due to the large amount of encouragement from 'lust' to get a large profit, so he sacrificed the security of his own account with the OP using large lots. If indeed our analysis is correct, of course, the desire to get a large profit will be realized, but if our analysis misses, the consequences that must be accepted are MC.
