Just in case anyone actually follows these threads this is the solution to Teds
question of a few days back. With the help of Marcin I was able to come
up with this weekly formula:
WeeklyBase = TimeFrameCompress( C, inWeekly );
SetForeign("!SPX");
TimeFrameSet( inWeekly );
RSEMA = EMA( ( WeeklyBase / C ) * 1000, 7 );
RestorePriceArrays();
RSEMA = TimeFrameExpand( RSEMA, inWeekly );
Plot( RSEMA, " WEEKLY RSEMA", colorRed, 8 );
which draws the same chart as this formula viewed with weekly display:
RS = RelStrength( "!SPX" );
RS = EMA( RS, 7 );
Plot( RS, "RS", colorRed, 8 );
