People here seem to like to use TA for trading forex. I don't understand the basic logic of why TA would work for forex (or anything else, but let's keep the focus on TA). I understand the usual defense for TA is "it's all in the price". Okay. I can sort of accept that for the pre-1990 timeframe. But these days, we have a very different market - with larger amount of hedging motivated trades (for both cross-country investments as well as hedging other derivatives) and algorithmic executions that are primed to hide itself. Why would the same basic patterns from the pre-automation days still hold? (I'm not looking for seeing a chart of some pattern along with a "look! it worked". That sort of reasoning is useless unless you can you show all the times that particular pattern has popped up, and then tally how often it actually worked).
