I post this to let you know, as the title mentions it, that I made a trading diary, with google documents tool. This a generic spreadsheet which allows any trader to manage his trading (his risk, his pnl, his opened position, the orders...) with a trding diary. Every trader,should have one, and I mad mine with google docs. At least you must have an account to acces this spreadsheet.
Back tests – You can read my forex robot reviews to see if the forex robot has back tests which will give you a good idea how it performed historically, some forex robots even back test as for as 15+ years! Ideally, you would want back tests to have been done using real tick data and spreads, thus making the forex robot back test results as accurate as possible in the mt4 strategy tester
