Backtest different from Live test

Hi,

I ran an EA live last night and it made a fair few trades...some winners some losers.

However when I backtested last night not all of the trades showed up!

Can anyone help to explain this phenomena?

I am using MBT - is there backtest data very unreliable - I have 90% modelling quality and no chart mismatches.

hey gangsta.... the answer is in the code....

we can make guess's like , spread, 0 bar, repainting indicators, tradecontexbusy and more..... all those will cause differences..... but we would only be guessing without seeing the code.....

very very few ea's backtest the same as forward test.... h

Backtesting assumes the following:

 

1. Constant spread
2. Stoplosses and Takeprofits are always hit at the price
3. Trades are always entered at their price.
4. NO slippage

If you didn't write the EA, look for something in the code called "IsTesting()", see what it's doing.
