I see many people trading crypto without using a tool that really makes a difference: Open Interest. Seriously, when you start tracking this along with price and volume, the game changes.

For those unfamiliar, Open Interest ( or OI ) is nothing more than the total number of open contracts that haven't been settled in the market yet. Basically, it shows how many active positions exist at that moment in an asset. And why does this matter? Because it reveals the traders' real interest there.

When you see OI rising while the price is also going up, it's a sign that something serious is happening. It means new contracts are being entered, fresh capital is coming in, and volatility could increase significantly. Now, when the price rises but OI drops, that's another story — it could be a short squeeze, meaning people are closing short positions, and then an unexpected reversal may occur.

I like to use Open Interest in three main scenarios. First, trend confirmation. If the price is rising and OI is following, the trend is strong, with new buyers truly entering. Second, liquidity analysis. When you have high OI but low volatility, it's accumulation. The market is quiet but concentrated, ready to explode in one direction or the other. Third, the liquidity hunt that the market does. Resistance or support regions with high OI? Be careful, the market might try to liquidate positions there before the real move happens.

The truth is, no one should look at Open Interest in isolation. It has to be combined with volume, funding rate, technical analysis itself. When you put all this together, the scenarios become much clearer and your decisions much more accurate. BTC, ETH, XRP — in any of these assets, OI is telling the story of what's happening in the market. You just need to learn how to read it.
