I found that metatrader and backtesting is looking like a devil saying yes and laughing at me.
I ran many expert advisors including the moving average that comes default with metatrader and when you run it over a few days with tick data or openprices I dont see the profit on report having the same number if you keep running it over and over on same days. The moving average expert just gave me around $900 then said $1000 and then the cents keep changing. So I dont believe metatrader is telling me the truth here. How can the numbers change if you are using mathematical equations and it keeps spitting out lies. How does it spit out lies?
If you run this on one day and you repeat backtesting I dont ever see the same number. What is the point of this? Im using 90% modelling quality. You can also use open price backtesting and keep firing that start button and you see it changing. I think its a waste of time for me to backtest with this nonsense, its like a little devil saying yesss! What other programs are out there to get correct reports everytime
Thanks for the answer but they must record spread in history to. Its giving me losses in one backtest and then profit in others, its nuts.
You can set the spread before running backtest I know but can you set that spread inside an expert advisor to the average spread of that pair calculated.
Spread is NOT saved in the history, only Bid prices. There are other parameters that can influence the results from a Backtest . . . the main one is Spread but not the only one. Read the thread . . . then repeat your test with a fixed Spread while disconnected from your Broker.
tick data backtesting is the way to go for the highest accuracy. But there are very few ways to do it. TickStory and Birt's Tick Data Suite with dukascopy tick data (or whatever source you prefer; dukascopy is popular because they make it easy to download and the quality is acceptable to simulate ECN spread and market conditions)
Mt5 doesn't even allow any 3rd party data, and that platform is supposed to be the more advanced one of the 2. Anyway, be glad that you can still use mt4 to simulate the strategies with tick data.
