The logic of $EDGE is completely correct. The liquidity on weekends is poor, dropping from a high of 1.19 all the way down to 0.86. I just didn't expect the project team to pull it up like this on Friday, and I set a stop loss that night because I was afraid the project team would push it up all at once. However, on Saturday, I continued to open short positions. The strategy over these past few days has been fine, but the practical execution still needs improvement.
