I just revised it in Wenhua Yingshun according to MA 1:MA(VOL, M 1), but it didn't work. Then I referred to the horse's index parameters and found something wrong. After modification? MA 1:MA(VOL，n 1)； Then write N 1 after the name in the parameter setting, and set the value yourself, so there will be no problem.

This is an average line to increase turnover. If you want to add positions for a while, you can change VOL to OPI or add another line? MA2: Horse (Opi,); ? Then add a parameter setting.
