I would suggest learning price action first and foremost, in particular, Japanese candlesticks for one particular market. Understand what the Open High Low Close patterns suggest amongst single/multi-candle setups then contrast that against different market backdrops i.e. trending or range-bound markets. You will start to hopefully get a "feel" for the market and pick up on "patterns" or "trends" that you will then, and only then, introduce indicators afterwards to vindicate your hypothesis. Remember, indicators are derivatives of the price action and as such, should be looked at after analysis of price action has been completed and not the other way around. If you wish to study indicators, Edwards and Magee "Technical Analysis of Stock Trends" is a good start because grasping the mathematics of the underlying indicator (not really hard tbh) is super important to understand not only what it does, but when it's best applied. E.g. RSI is best in a range-bound environment, moving averages in a trending one, etc.
