You describe just how I was in the beginning :)
If you are just starting with EA Studio you will be surprised with many more things with that software.
When you have an Expert Advisor and you backtest Forex strategies with it, it is really nice, you see the results. But you do not get the bigger picture. With the editor in EA Studio you see every change you make and how it impacts the strategy. Let’s say you change the SL from 50 to 60 pips and one click you see the backtest, the Output with different parameters as Profit Factor, Max Consecutive losses, and many others. You can not really see that in MetaTrader…
Backtesting Forex strategies has really improved and this software gives so many opportunities.
