My argument is with TA users who think they are quantifiably increasing the odds on an entry. This can not be shown or proven--
Quote from marketsurfer:
Charts are descriptive, not predictive---
I think I finally understand what you're arguing and you are correct! Charts are absolutely not predictive. Nothing is predictive. No chart pattern or indicator or combination of patterns/indicators or news release or massive depth/height to which price has dropped/risen can predict
with certainty what price will do next.
What you're missing, Surf, is that experienced, profitable TA traders DO NOT believe they can increase the odds
on any individual entry.
The odds of any trading plan are based on what price has done in the past
more often than not over a period of time that encompasses a wide variety of market conditions. A variety of market conditions includes strong trends with shallow pullbacks, channeling trends with deep pullbacks, wide ranges, narrow ranges, bull runs and bear runs.
When a student of PA/TA finds, through extensive and diligent
documented research, that certain price and/or indicator patterns (setups) create a sufficiently profitable move to overcome the deficit of a logically placed stop loss (plus commission and slippage)
more often than not, the student prepares a trading plan that describes the patterns, entry methods, and trade management techniques to exploit this edge.
The student trades these patterns (PA/TA) according to the plan.
Once the student overcomes the basic human instincts that interfere with success in the uncertainty of the trading environment, s/he eventually attains a mindset and reaches a level of experience with that mindset which results in consistent profitability.
This trader's mindset means you trade your plan despite personal bias/opinion, and you fully realize that:
1. Anything can happen
2. You don't need to know what is going to happen in order to make money
3. There is a random distribution between wins and losses for any given set of variables that define an edge
4. An edge is nothing more than an indication of a higher probability of one thing happening over the other
5. Every moment in the market is unique

So I agree with you that charts are not predictive and I believe that you are right to alert any trader who believes s/he can increase the odds on an entry that this a very dangerous belief in trading.
Odds are based on X number of trades, not on any individual entry. A common complaint on ET is traders who have losing trades then skip the next appearance of their setup, and of course it's the good one. Picking and choosing trades from a basket of valid setups destroys any edge.
