//  Modified by st2050
//  v1:  Changed MAprice from integer to ENUM_APPLIED_PRICE
//       Can't add ENUM_MA_METHOD for sMAtype due to LSMA support
//       Added MaxBars parameter
//       Added ShowOnLineModeOnly parameter
//
//  v2:  Added "Do not draw current candle" property
//
//  v2.1 Added missed "if (limit= 1  ; i--)
