I remember George Angell was selling something in the 90's for $10 bucks, he made over $250k with that. George was one of the very few better vendors as if you didn't like it, he refund you. I meet George in 1995 in Key West, he wanted to do something together, but my knowledge of options wasn't enough, plus I had other ventures going on. He then met up with George Fontanills living with his mom in small trailer park, OMG, that was a bad deal for Angell. The programming for the stocks-futures/options software was the worst, so refunds were coming in leaps and bounds, but Fontanills would not anty up his 50% of the refunds, Angell dug even deeper and covered all the refunds fully, to me he was class act. I have always thought he was better long term futures trader than day trading though he did work in the pit at a time. Fontanills was more of a salesman of his $4k option system and some educational school, but just cause you have a MBA in Finance don't make you knowledgeable of the markets.
I still say, the wrong people buy trading systems, newbies don't have knowledge of when they have to adapt, quoting EMG "They just lose". I have bought trading systems and have made changes in how they traded, I trade depending if they have reach "mean" drawdowns and if past back testing show they make a "mean" equity swing from the lows, I continue to trade them till they reach that mean average and quit till another mean drawdown.
OMG am getting older, LOL
