afaik Ross never stated that he's 100% kosher. on the contrary, his website states: 'results may be based on simulated or hypothetical performance'
Ross is fake and/or a scam. In his videos, he shows getting out at prices that are nearly impossible especially with the volume he was in...
If you watch madaz videos(at least the ones I've watched) where he record his live trades, you can see the volume and prints. So his entries and exits are reasonable and would be able to be filled. I don't see those on Ross...
