I tried to compute the projection oscillator for 15min frxGBPUSD candles, the total number of candles were 5000, in number. The projection oscillator returns negative values and values greater than 100 PO values range should be [0 -> 100] . The package function package.projectionOscillator returns an object res = { po:[ items ], spo:[ items ] };

1. The res.po returned 227 <= 0 and 615 >=100, sample arrays as follows respectively.
   res.po less than 0
   

res.po greater than 100

2. The res.spo returned 227 <= 0 and 610 >=100, sample arrays as follows respectively.
   res.spo less than 0
   

res.spo greater than 100
