Hi Alan, having too many strategies really isn’t much of a problem. But lets say the you are aiming for roughly 1000 strategies in your pool per symbol timeframe pair.
If at the end of the month you have 2000 and want to trim a bit you could load your existing collections into the validator in chunks to get the best 250-300 and then just keep the final 3-4 collections that come out of the validator. Also as you will be moving the validator end date forward a month some may just naturally fail the acceptance criteria and if you are getting too many passing you can simply increase the acceptance criteria a little and filter the top 300 however you want when you run them through the validator.
How many strategies are you expecting to have??
