you can code that like:
condition = BarsSince( C > Ref(C,-1)) == 3 AND MA(V,3) < MA(V,50);
Buy = Ref(condition,-1); BuyPrice = O;
SetChartOptions(0, chartShowDates);
Plot(C,"C",1,64);
PlotShapes(IIf(Buy,shapeUpArrow,0),colorWhite, layer = 0,
yposition = BuyPrice, offset = 0
);

goes like this:

days in a row
