i just copied ur formula and placed in amibroker 4.9 i dont find any syntax eror its working fine

 

[Jagdish Patel]

i have amibroker 4.8 i attechhed its screenshoots

 

[toptrader]

try to delete the entire line, setbarfillcolor also with ami 5 is not possible i just delete the line and the formulas go ok, setchartbkgradientfill perhaps is the same thing

unfortunately I know, if you don't find someone that adapt the formula to your amibroker version is the only thing to be done, unfortunately every version has some functions that even the preceding ones didn't have

try also to sobstitute all lines with "SETCHARTBKGRADIENTFILL" with "SETCHARTBKCOLOR"
