PaintBar or ShowMe bar code?

Can someone help me code an indicator for a simple 15 minute bar reversal, someting like if this bars low is lower than previous bars low and close is greater than previous then....im not sure..paint the bar? or show a dot? or somehow point to it...
Thankyou

Sadly I don't think paintbars are supported yet so I guess that leaves a dot. Personally I would have preferred to see basic stuff like paintbars rather than fancy stuff like genetic optimisations (I have expensive software that does that gathering dust on the shelf) but I can understand how from a marketing point of view the latter may appear more exciting.

Cheers,
Nick.

If (conditions) then
PlotPaintBar(H,L[,O,C[,"Name"[,Color[,BackgroundColor,Width]]]]);

Normally I just do PlotPaintBar(H,L,O,C,"somename",Color);

This takes up Plots 1-4, so if you're using the same code to plot other things, start with Plot5(whatever).
