rule No.1 Must stop loss, ETH 40 points, wrong is wrong

rule No.2. Most of the time during major market movements, the teachers are accurate, but stop loss > teachers, hard losses, at worst just re-enter.
rule No.3 set and forget, be prepared for stop loss or take profit, either stop loss or take profit.
rule No.4 If there is no direction, it's better not to act. Seizing one opportunity can earn you more than watching the market all day.
rule No.5 The teacher's points are very vague, and if it can't go down, one must be cautious of a rebound. Ultimately, it still requires personal judgment. Just follow the direction of the teachers. It's very difficult to enter; some points are very wide. Either the points are set before placing an order, not giving an opportunity (this requires judging the entry and exit profit-loss ratio; if suitable, enter at the current price), or it has surged past the entry point (either the entry has become narrower, or the direction has changed).
