In the morning, add positions during a big drop, reduce positions during a big rise.

In the afternoon, only reduce positions during a big rise, buy on the next day after a big drop.

Do not sell coins during a morning drop, add positions on dips T+0.

Do not chase prices during an afternoon rally, reduce positions on highs T+1.

Watch for 10 AM during morning rallies, watch for 2 PM during afternoon rallies, sell at the highest point. If the coin is strong, seal at 10 AM; if the coin is weak, seal at 2 PM. Control positions without being reckless, rolling operations are the best strategy.

Do not short in a bull market, do not hold long in a bear market.

Do not panic sell in a bull market, do not chase prices in a bear market.
