Been trading crypto for a while now and I keep coming back to order blocks as one of the most reliable concepts I've found. Honestly, when you understand how these work, it changes how you read the market.

So here's the thing about order blocks - they're basically the last candle before a big impulsive move that breaks market structure. When price makes a higher high or lower low and then reverses, that final candle before the move is your order block. But here's what most people miss: price actually has to break structure for it to count as valid. If there's no new HH or LL, it doesn't qualify.

The reason order blocks work is institutional money. Banks and large traders place massive orders at these levels, so price naturally gravitates back to rebalance and fill liquidity. It's supply and demand on a technical level - when you see a bullish order block form, institutions have stepped in on the downside, and price will eventually return to that area before continuing higher.

What I've learned from testing is that the newer, untested order blocks hit better than ones price has already come back to multiple times. An untested supply or demand zone is way more likely to give you the reaction you're looking for. And here's a solid rule: if price fills 50% of the order block, you can mark that one as mitigated and stop watching it.

Let me break down what a bullish order block actually looks like. It's the last down candle before price impulsively moves up and breaks structure. You'll see strong momentum to the upside, which leaves behind price imbalance. What you do with it is simple - enter at the top of the bullish order block, put your stop loss at or just below the low. That gives you a clear setup with defined risk.

Bearish order blocks work the same way, just inverted. Last up candle before a bearish impulsive move down. Price breaks structure, momentum carries down, imbalance forms. Entry at the top, stop loss below.

Timeframe matters too. A 4h order block is going to be way more reliable than a 15m one because the higher timeframe, the more significant the zone becomes. I've seen 4h order blocks lead to massive moves while lower timeframe setups only give you small reactions.

One technique I use is refinement. Sometimes the momentum doesn't engulf the entire order block, so you can zoom in and refine it down to where the actual momentum entered. This gives you a cleaner level to work with.

The key is patience - wait for untested areas, confirm your market structure, and only take trades that align with the bigger picture. This is how I've been consistently profitable in crypto trading.
