what is the quality of beck testing

[daglas]

Dear friends.
Can you say me what is the level of quality of beck testing?
How much real time testing results and back testing results differ from each other.
I create a few strategy with 0 draw down and 100 % percent profitable trades. Can I get such results in a real time trading? I have include commission and sleepage.

Hi Daglas,

Yes, there are discrepencies expected when backtesting compared to real time. It's easy to form fit conditions to produce positive results. Backtesting is a good starting point, and can break down performance of your strategy in a lot of different ways. But you should always forward test in real time or with a market replay connection to get an idea of how it operates with streaming data.
