Market trends are constantly changing. To follow the trend, you need to seize key positions. Today, I have summarized some trading ideas for mainstream contracts for your reference.

**BTC Contract Trading**
Currently, bulls need to hold the 90200 support line. Once confirmed to be solid, the targets are 91000 and 92000. Conversely, if it falls below 89300, the bears gain the upper hand. Pay attention to the downside space at 88500 and 87800. The range is prone to being trapped; it is recommended to wait for a clear breakout before following.

**ETH Contract Rhythm**
Use 3050 as an important reference level—only after effectively breaking above 3050 can bulls have room to operate, with targets at 3120 and 3180. If it falls below 2980, then focus on the supports at 2920 and 2860.

**SOL Contract Boundary**
128 is the key dividing line between strength and weakness. Bull investors can look for light long opportunities when retracing to the 128-129 range, targeting 133 and 136. Once it falls below 127, bears become profitable, with targets at 124 and 121.

**ZEC Contract Strategy**
350 is a critical position. Above 350, oscillations tend to favor bullish thinking, with targets at 365 and 375. If it falls below 348, then look down to 335 and 325.

**Trading Discipline Reminder**: Do not act without a clear breakout. Follow the trend after a breakout. Cut losses decisively if wrong, hold tight if correct—this is a fundamental principle applicable in any market environment. The market logic is there; using rules to navigate bull and bear markets is much more reliable than blindly chasing highs or selling lows.
