I can run a back test to get the info you need. But which instrument/stock etc are you looking at. Each stock, currency or futures behaves differently and buying power and margin for them are also different.
Also theoretically automated system works. But practically you have to know that technical/system/communication and human intervention can happen that could mess up things. Slippage when stocks move fast, internet connection could go down, and if it is a unregulated market like forex, brokers can mess with your orders, as it happened to me which is the only reason why I left forex market after 7 yrs of trading it. Let me know how I can help you.
