If you look back to a swing trading range and lock in at 3 points, when entering in batches at buy low, do not evenly distribute the bullets, instead, fewer bullets should be used at higher price points, and more bullets at lower price points. For example: if ETH falls below 2412, then you should wait to enter at 2380, 2350, 2336/2330. If you use 3000u bullets to enter, then 500 should be used to enter at 2380, 900 at 2350, and 1600 at 2336. This way, the average price will have an advantage, making it easier to profit from the rebound. If you enter with an average Position, even if all three points are entered, the average cost of the Open Position is relatively centered, with no significant advantage.

And if you want to entrust Open Position with 3000u at 3 points, then the Margin should be at least 7000-10000. Now the eth trend is bearish, short-term long order Liquidation should be controlled above 300-400 points to prevent big needles. However, each low long order should make a defensive reduce position of 25% near the support level below the third low point, which can effectively avoid being trapped in Lock-up Position when it falls through more than 2 support levels continuously.
