I am new to this forum and trading. I may put this thread in a wrong section or asking an irrational question. Here is my question. I have an IB account. I have 2 strategies. They will recommend buy / sell stocks everyday. Some stocks are overlapped, so there may be a situation that strategy A suggested to buy Stock Z 100 quantity and later on strategy B suggested to sell Stock Z 100 quantity. If I put these 2 strategies into one account, it seems that a collision will be happened. If I separate different strategies into different accounts then I will need many accounts if I have many strategies. Also, how to decide the among of capital for each account? I would like to ask what is the normal way to due with this kind of situation. Thank you very much.
