Wake up! All trading systems are 'expired cans' 1. The market is never a puppet that follows a script. The trading systems that claim to be "one move, one delicacy, all over the sky" are essentially scales engraved on the mobile deck - when the tide recedes, only ridiculous misalignment remains. 2. Technical indicators may collectively defect, K-line patterns may distort at any time, and even the most reliable moving average can perform a "backstabbing" drama. In this battlefield full of human games and sudden black swans, there is no eternal formula for solving problems. The glorious achievements of a certain period are just a temporary "survivorship bias" given by the market. 3. Traders who mechanically execute the 'Holy Grail System' often become the target of market sickles. The true password for profitability lies in dynamic adaptation: flexible adjustment of strategies, iterative trading cognition, and using judgment to open up new paths in the fog of long and short positions. Remember: the system is just a crutch, not a wing. When you persistently search for the "perpetual trading machine", the market is already at the corner, preparing a thorny crown of thorns for those who cling to dogma. BTC
