[SQ 136Final] MA indicator lookback error when generate souce code for Powerlange

1. I developed a strategy on sq and made a further backtest on MC, and found that the two were quite different. After a transaction-by-transaction comparison.I found that the problem was with the moving average indicator.Please see the attachment.This strategy uses a custom block: MA[1]*0.99<close[1]<MA[1]*1.01,But when sq generates the Powerlanguage code, it becomes MA[2]*0.99<close[1]<MA[2]*1.01. After comparing with MC's backtest, I think SQ's engine is still in accordance with  MA[1]*0.99<close[1]<MA[1]*1.01.,only generate fault souce code.

2. In addition, I don't know the difference between MA indicator and SMA indicator in sq. It seems that there is no difference in notes. The only difference is that the lookback of MA indicator in the code is not correct.
