There are five iron rules for opening a contract position:

First, do not open a position without a breakthrough;

Second, do not open a position without a stop loss;

Third, do not open a position if the stop loss is too large;

Fourth, do not open a position without a signal

Fifth, do not open a position before reaching a critical position. #BTC走势分析 #合约爆仓 #炒币技巧
