SUNW P&F Chart (Box=1, Reverse = 3)
Below is the code to chart only Stocks.
You can control the right margin space for PF Chart, Last value close, Horizontal Grid, and Price Axis through variables:
shiftChart =0;
shiftLastClose =1;
shiftGrid =7;
shiftPriceAxis = 2;

shiftChart =0;
shiftLastClose =1;
shiftGrid =7;
shiftPriceAxis = 2;
