I just realized that many new traders often overlook a pretty useful indicator: RSI. This is a tool I use quite frequently to assess whether the market is hot or cold.

RSI, or Relative Strength Index, is a momentum oscillator that ranges from 0 to 100. Its great advantage is that it helps you see whether a coin is overbought or oversold. When RSI exceeds 70, it’s usually a sign of overbought conditions; when it drops below 30, it indicates oversold conditions — these two levels are quite important for identifying reversal points.

The RSI calculation formula isn’t very complicated. Basically, you take the average gains over a period divided by the average losses over the same period, then apply the formula: RSI = 100 - 100 / (1 + RS). I usually use a 14-day period for this calculation. This RSI formula is quite standard and adopted by most platforms.

In actual trading, I find RSI most useful when combined with other indicators. For example, when RSI approaches 70, I also check what MACD or Bollinger Bands are indicating. If all three signal overbought conditions, the likelihood of a price decline is quite high. Conversely, when RSI is near 30 and other indicators also confirm oversold conditions, that’s a good time to enter a position.

One thing to note is that RSI can stay in overbought or oversold territory for a long time if the trend is really strong. I’ve seen some altcoins with RSI above 80 for several weeks because of a very strong uptrend. So, don’t rely solely on RSI to make decisions.

In my strategy, I use the RSI formula by first monitoring when RSI approaches key levels, then cross-check with other indicators, and finally decide whether to enter or exit a position. This helps me avoid false signals and improve my win rate.

If you’re just starting out, try adding RSI to your chart and observe it for a few weeks. You’ll gradually understand how it works and when it’s most reliable. Crypto trading requires patience and continuous learning.
