confused about backtest

[274275025]

Hi,

I m new here but I use tickstory some month,and i really like this because very easy to work.

I have a confused recently,I try to backtest same ea,same setting input,same spread and same broker,why result are huge different?
one is BT via tickstory ,another is BT with pepperstone tickets with Birt's "ticket date suite"
tickstory: good result,low max DD,99.9% quality.
pepperstone tickets with Birt's "ticket date suite": margin call,99% quality.

my test broker is pepperstone...

so which backtest result should be more close with real history?

Hi there,

You may get discrepancies between Birt's Tick Data Suite and Tickstory if you are using variable vs fixed spread. If you are using a scalper, it may well be very sensitive to spread and therefore showing you favourable results when testing with say 1 pip fixed spread. You should try a few back-test variations to increase the fixed spread to see if your EA's performance degrades.

Hope this helps.
