For beginners doing ETH, the forced liquidation of long orders is currently controlled below 3400. About 20% of the position, with 20 times as the benchmark. If you lock in 3 points to take more on the same day, 3 points (within the same small band, around the support level, they may all be touched), clearly stated that they all need to be taken, then the total position of the 3 points is 20%. If you only lock in one point, enter the market at 10-12%, and when the price continues to rise after floating profit, you can add to the position at the current price as appropriate, and stop profit near the nearest resistance point.

In a strong market, the first position is 6-8%, the position is 10%, and the real-time position is 3-5% (the support is relatively strong, the retracement is small, and it is constantly at a new high. The position is in floating profit, and it is appropriate to add to the current price as appropriate).

Later, when BTC starts to break through 10w or more and the market is very strong, it can be raised to 25%*20 times. It is not recommended to have a position with 100x leverage exceeding 15%.
