Very true!
The result of backtesting offers statistics that can be used to gauge the effectiveness of the strategy but then past performances does not necessarily guarantee good results always.. Not always a hundred percent accurate. So make sure to try it out first before going live.
Good luck!

In my opinion, backtesting is worthless for its results.
There's only 2 ways the backtester is usefull:
1. For coders who wants to test the logic of their coding.
2. To observe how an indicator react with the market movement (example to see if it repaint).
About results, keep in mind that in backtesting, you won't have all the "hunting" issues from brokers. No spread spike, no stop hunt, etc ...
This is what makes backtesting and live results so different.
