Short answer: read a chart from the outside in. First the trend on a bigger timeframe, then the levels price keeps reacting to, then where price sits between them, and only then the indicators. Finish by naming the price that would prove you wrong.
Before you look at the chart you plan to trade, open the next timeframe up. If you trade the 4-hour chart, look at the daily first. A rally on the 4-hour chart inside a daily downtrend is usually a bounce, not a new uptrend. Most bad reads come from skipping this step.
The trend is simply the pattern of swings: higher highs and higher lows is an uptrend, lower highs and lower lows is a downtrend, and anything else is a range or a coil. See market structure for how to mark the swings.
Look left on the chart. Where did price turn more than once? Those prices are your support and resistance. Two or three clean levels are worth more than ten faint ones. The nearest level below price is the floor, the nearest one above is the ceiling, and together they make the box price is trading in.
Price pressing the floor, price in the middle, and price pressing the ceiling are three different situations. At an edge, the next candle closes either confirm or break it. In the middle, nothing is decided and most moves are noise until one edge gives way.
Indicators like RSI and MACD describe what price already did. They are useful when they disagree with price — a new high that momentum does not confirm (an RSI divergence) is a real warning. When they simply agree with the trend, they add little.
A read is only useful if it says what would change it. "Higher while price holds above X; a close below X breaks it" is a read. "Looks bullish" is not. Always use closes, not wicks: a wick through a level that closes back inside is often a liquidity sweep, not a break.
Open any of the live market reads — for example Bitcoin or Ethereum. Each one follows exactly these steps: the bigger picture, the box, where price sits, what momentum adds, and the closes that would change the read.
There is no best one — use two. Read the trend on one timeframe up (the daily if you trade the 4-hour) and act on your own timeframe. Short timeframes like 1-minute and 5-minute are mostly noise for anyone who is not scalping.
Start with none. Learn swings and levels first; then add RSI to spot divergences. Price and levels explain most of what indicators show, a little earlier.
A single candle means little on its own. A candle that rejects a level price has respected before means a lot more — location matters more than the shape.
