i bought his book, and only some of the ideas presented could be backtested (I think there is one where if you get three up bars on some short-timeframe intraday go long, and opposite go short), they did no better than random or worse.
Most of the idea presented couldn't be quantified or tested for edge or tested no better than random.
I see a lot of hype about Mr. Carter + Senters (I did buy the Senter's 'squeeze' strategy) but the information I've seen by them makes it seem like they are giving you a lot of info but seemingly always is missing something to actually make it work in real life.
Anyway, I remember I paid I think $70 for the book and I recently gave it away. Just upset I paid so much for it, bought it because I thought the guy might be legit.
I don't know if he is or not, but I decided to avoid them because I could never understand their strategies or what I could test quantfiably gave random results. So maybe if they have good money managment that is really their edge.
