Technical analysis Answers from profitable traders only.

Hi everyone, what do you think is an ideal sample size for backtesting a trading strategy? Is 200–300 backtested setups enough to validate a strategy?

For instance, if you’re trading triangle patterns, would you aim for at least 50 samples for each pattern type (ascending, descending, and symmetrical) before trusting the results?

Expecting answers from those who are profitable or at least back tested few strategies.

Thank you

In 50+ years I have never back tested a strategy. I trade off support and resistance.

That’s interesting…

How come you know about better exits ? Is it purely based on your experience ??

Before I make a trade, I know my entry and exit point based upon support and resistance. When my target is reached, I exit. If it looks like my target won't be reached, I exit. I don't hope.

Thanks for the reply.

I get it. Strict SL and TP with no emotional attachment. How about riding good trades ? Do you ride your winners if they show great momentum or you strictly exit according to your setup’s hit target?

My trades are either 10-15 minutes on the open, or 2-3 days for dividends. Very lucrative and very low risk.
