Back-testing Question for a beginner?

Hello All -

I’m new to backtesting. Is it best to backtest my strategies including any indicators or price action strategy I may use on a RANDOM currency pair I’ve never traded before. This way, I’m assuming, I won’t have any bias on it’s direction?? For example, if I’ve always traded the USD/CAD pair I might know its long term direction already?

Also what is the advantage of multi-time frame back-testing and should I focus on smaller time frames and look primarily at 1hour or less bars so that I actually see more movement in the day to actually test my strategies??

Thanks in advance.

Bit of a silly Question really
Do “you” think you should back-test.? @S100

Yes i Would recommend Back testing any of your strategies also if your using the MT4 built in back tester it can test all time frames in your test plus give you suggested Optimization.
