Novices must strictly follow the rules to open a position (about 12%), cover a position (about 13%), and make a second payment (10%). Don't keep adding positions during the process of raising prices. This kind of position management can resist the continuous breakthrough of 3-4 support levels. There are basically no callbacks that can break through 3-4 support levels in a day, so it is relatively safe. Only black swan can be realized, but the condition it is in is that the 2 and 3 day line MACD returns to zero axis, which is currently not met.

In an emergency downward trend, and when the correction trend may continue further, we need to retreat to the next support level and make emergency preparations in advance. When it is time to cover the position, you must cover it in time to reduce the cost, be decisive in killing, take advantage of the 30-minute counterattack opportunity to stop profit and reduce the position, and then ambush the position near the next support level to cover the position to continue to reduce the cost of opening the position. SOL rebounded to 116-117 twice yesterday, so it is safe to reduce the position by half. If you miss twice, it will be difficult to get a third chance, so you must kill decisively. In the middle of the night, I stepped back to cover positions near 106 and 100. Now the cost of opening a position is below 107. The resistance today is 112. I will continue to take profit by half, and then ambush a second dip near 101 and then take a low long position. Take profit at 108-109. .

In an emergency, when the margin is insufficient or multiple positions are heavy, open short-short hedging to save the long positions and delay the forced liquidation. If you lock the position, you need to manually reduce the position, and immediately open a short-term buffer for the reduced position, so that dangerous positions can survive the difficulties.
