Thanks much - did the trick!!!
After shooting a few other bugs and nice-ifying a bit, here's my final version of the code. It appears to work as intended now.
LongLeg = Param( "LongLeg", 35, 1, 200, 1 );
ShortLeg = Param( "ShortLeg", 5, 1, 100, 1 );
MultiLeg = Param( "MultiLeg", 10, 1, 200, 1 );
MultiW = Param( "MultiW", 1, 0, 2, .01 );
BClr = ParamColor( "Band Color", colorRed );
ShortWeight = 2 / ( ShortLeg + 1 );
LongWeight = 2 / ( LongLeg + 1 );
SyncShort[ 0 ] = Close[ 0 ];
SyncLong[ 0 ] = Close[ 0 ];
for( i = 1; i < BarCount; i++ )
{
SyncShort[ i ] = SyncShort[ i - 1 ] * (1 - ShortWeight) + (ShortWeight * Close[ i ]);
SyncLong[ i ] = SyncLong[ i - 1 ] * (1 - LongWeight) + (LongWeight * Close[ i ]);
};
MultiOsc = (100 * ( (SyncShort / SyncLong) - 1) );
Plot( MultiOsc, _DEFAULT_NAME(), ParamColor( "MO Color", colorBlue ), ParamStyle("Style") );
MultiWeight = 2/(MultiLeg + 1);
SyncMulti[ 0 ] = MultiOsc[ 0 ];
for( i = 1; i < BarCount; i++ )
{
SyncMulti[ i ] = (abs(SyncMulti[ i - 1 ]) * (1 - MultiWeight)) + (MultiWeight * MultiOsc[ i ]);
};
MultiHigh = SyncMulti * MultiW;
MultiLow = -1 * MultiHigh;
Plot( MultiHigh, "MH", BClr, ParamStyle("Style") );
Plot( MultiLow, "ML", BClr, ParamStyle("Style") );
