if someone is telling you price HAS to do something don't listen to them (sometimes thats me as i get cocky and forget then J reminds me). 80% is the highest probability and that is low enough to wipe out a trading account...

trading charts is the same as going to a rent auction for your ground every year only the rent auction is more risky with yield variability... it helps to know HOW to make that scenario work but i would hate to depend on those margins to make up my income.
