I think that this one should be the same: Projection Oscillator

if you compare CCJ daily in proreal up to yesterday you are going to see difference (it is actually pretty large one) in way of plotting.

Most likely the data feed that you are using in ThinkOrSwim is not identical to the data feed to your PRT platform and if you don’t put the same thing in then you can’t expect to get the same thing out. If the indicator calculations are the same calculations then this can be the only reason for a difference in output.

P.S. French is not needed as you are in the English language forums and the rules say….

The real formula used by TOS would be great. In the meantime, you can try this version I just coded by gathering ressource on the web:

period = 14
pboPeriod = 14//user defined, default is 14
price=customclose

mHigh = linearregression[period](high)[1]   //returns the slope (m) of Linear Regresion 
mLow = linearRegression[period](low)[1]
count = 0
pbw = 0
pu = 0
pl=0
for i = 0 to pboPeriod + 1 do    //move back 1 period
hhigh = high[i]
llow = low[i]
vHigh = hhigh + (mHigh * (count))
vLow = llow + (mLow * (count))
if (vHigh > pu) then 
pu = vHigh
endif
if (vLow > pl) then 
pl = vLow
endif
count=count+1
next

PBO = 100 * (price - pl) / (pu - pl)

return pbo
