At the end I will attach a youtube video guide how to use the tool and show you how to backtest xau usd spread alpari forex practice. Many trader struggle to backtest correctly.
When I remember back, some years ago it has been a difficult task and it took ages to set up the tick data etc. Use a 3rd party application to obtain free high quality Tick Data and the tool that you can use to test. The market for this is not huge. You will appreciate what I am talking about if you try out other 3rd party applications.
Your tests look good, but Your live results fail . When it comes to Tick Data quality it is obvious that we need the best possible data that matches with our broker, since we want to evaluate and optimize our strategy on this data. Dukascopy, Alpari, TrueFX and in future many other data sources, or can add custom data sources and download it very simple and fast. You can always update your data by pushing the download button and it will only add the new to your existing data in less than a minute. I remember using tickstory or the old TDS Versions, with some 600 GB disk space for the same data.
