I developed a trading system in TradeStation using TradeStation data. The idea of running it in automated mode on Multicharts. My broker is Oanda. However, when I ran it on the broker’s data a profitable system turned into a losing one. Now I am lost in regards to what to do. TradeStation data is quite clean, so the system is probably valid. But how do I execute it? Runthe data feed off TradeStation and execute on Oanda platform? Or use the Oanda data for signals and execution? Or re-design the whole system based on Oanda’s data?
You should use the signals and data of your broker for working with your trade system. Automated charts may turn out to be quite useful in the coming time when you diversify your portfolio more.
