Price charts are extremely valuable. All charts are useful and with added MA’s, s/r levels, trends, patterns, candlestick patterns and indicators etc. are your technical analysis and all tell you something which can help in your trading. But you will lose money if you mix up their purposes -
- predictive - TA which tells you what price will most probably do next, so it’s also opportunistic
- opportunistic - TA which shows you what could be a great trade, but it’s definitely not predictive
- confirmational - TA which shows you what has been happening just now and recently and historically, maybe for years and years, but that’s all
When you look at someone else’s TA, first identify what their TA is aimed at doing. And it is NOT always making you money.
