You are using this:
C: > Program Files > OandaMT > MQL4 > Indicators
This will only work if you run mt4 in the portable mode (!), otherwise the folder is somewhere at
C:\Users\USERNAME\AppData\Roaming\M etaQuotes\Terminal\UNIQE-TERMINAL-HASHCODE\MQL4\INDICATORS
pls. check again,
PM me with coding requests and I'll probably put you on my ignore list
