BNB: Needle the daily MA90, update position management

Looking at BNB, the idea we gave yesterday was to ambush long orders along the daily MA90. From the current point of view, BNB finally stepped on a wave of MA90.

In the recent uncertain market situation, it is best to continue the logic of not being willing to fight in the short term and doing a good job in position management. For players who have received long orders, remember to set a protective take profit at the cost position, just like the previous short order at 257. After good position management, even if you may miss some potential meat, you will never take the order or lose money. Give the money to the dog farm.
