Shorting small crypto after pump

Hi everybody! I try to upload image of Mai trading history if you see it here I have been shorting small crypto coins that pump hard and then they dump. This has been working good so far the last 4 months with around 300 trades. I wanted to add some more confirmations and therefore asking you if you have any ideas what I can add? If there is some indicator about bag holders selling or tape reading from all crypto exchanges combined? -Judge-32 link
