#交易教学 You must understand the key support and key pressure when trading. Just like the bearish trend of the big cake last night, Brother Lie told the brothers that it is bearish if the key support is broken! If you do not do any risk management after breaking the key support, then your position will most likely be in a dangerous situation, and the heavy position may even be liquidated and return to zero! So, if you want to do a good job in trading, you must understand the key support and key position, otherwise you may end up with nothing at any time, and your profit will be withdrawn and you will lose money!
