-MOST indicator advised to use with Variable Moving Average in the sideways market by its developer Anıl Özekşi, so there are a couple of alternative Moving Average OPTIONS to use in the calculation of MOST:
"SMA", "Bollinger Bands", "EMA", "SMMA (RMA)", "WMA", "VAR"
SMA: Simple Moving Average
EMA: Exponential Movin Average
S+MMA (RMA: Smoothed Moving Average, Rolling/Running Moving Average
WMA: Weighted Moving Average
WWMA: Welles Wilder's Moving Average
VAR: Variable Index Dynamic Moving Average aka VIDYA
