Trading Systems and Consecutive Losses

I’m trading a 30 minute EMA cross system that I’m happy with using custom software. Last week with GBP confirmed what I’ve seen in testing: dealing with three or four straight losers. I’m just curious if anyone has experience with giving the averages “time to reset” after a losing trade. Im trading my systrm agressively so drawdowns are expected. Again, I’m not looking for holy grail, just interested in thoughts on automated trade strategies such as not taking another same trade within the same day, week, after a string of losses.

What are your MA lengths?

5ema and 21ema. Mostly focused on Pound and Euro
