Best Backtesting Software

I have used the forex tester to back test to begin with the forex trader.

1. The user interface is similar to MT4/5, easy to start testing. You can perform all normal operations same as MT4 or MT5
2. It has News option with all economics releases details. This I found personally useful as I am fundamental bases forex trader. I guess its unique. See the attached
3. For instance you want to check past effects of NFP releases on any forex pair its useful. I remember days I have scroll back the chart and match EST and GMT to check how the NFP release affected the USD pairs and Gold.

I've been using TradingView's "Bar Replay" feature to work on my manual backtesting. Since I pay them already for my charting, I figured it was better to stick with their backtesting feature instead of purchasing a new product.
