Been diving deep into technical analysis lately, and I think the 123 rule combined with the 2B rule is honestly one of the most practical frameworks for catching trend reversals in crypto. Let me break down what I've learned.

First, understand that markets move in layers. You've got the main trend that can last years, then corrective trends spanning weeks or months, and finally short-term noise happening daily. Most traders get caught up in the noise and miss the bigger picture.

Here's where the 123 rule comes in handy. It's basically asking three simple questions: Is the trend line broken? Are we making new highs or lows? Have we broken through key levels? If you can confirm any two of these, you've likely got a reversal brewing. The beauty of it is that the order can shift around, but you need all three conditions eventually confirmed.

Now, the 2B rule is where things get interesting for early entries. This one signals false breakouts, which happen constantly in crypto. Picture this: price shoots above a previous high (first breakout), then quickly pulls back below it (second breakout). That's your 2B rule in action. It's like the market is testing your conviction before the real move happens. The 2B rule gives you an earlier warning, but honestly, the risk is higher, so you need to be careful.

The smart move is combining both. Use the 2B rule as your early warning signal, maybe take a small position to test the waters. Then wait for the 123 rule to fully confirm before adding more size. This way you're not betting the farm on early signals.

A few things to keep in mind though. Trend lines are only as strong as the number of points they touch. Two points? Weak. Three or more? Now we're talking. Also, the crypto market moves crazy fast with huge swings in sentiment and volume, so these rules need context.

Risk management is non-negotiable here. Whether you're trading off the 123 rule or waiting for 2B rule setups, always use stop losses. Test with small positions first. The market rewards patience and discipline, not recklessness.

I've been using this framework on Gate to track some of the moves, and it's helped me avoid a lot of fakeouts. The key is understanding that these aren't magic formulas, they're just tools to help you read what the market is actually doing. Keep learning, keep testing, and eventually you'll develop your own edge.
