On 12-7 I noticed an anomaly in SPY( using IQ feed data )- I only noticed it because I use a study that measures relative time spent outside of VWAP deviation bands. Shortly after the open the Deviation bands merged into VWAP( Based on the SC VWAP study)- Using the ECI Vwap study showed a completely different result, however, later in the day both SC VWAP & ECI are correlated almost 1-1. -See attachment- IQ Feed Data SPY 10sec 12-7 I then ran the same scenario using SC data- Here the Deviation bands didn't merge into VWAP, however, they still show a different result vs ECI -See attachment- SC Data SPY 10sec 12-7 Exacting data out from Deviation band 1 you can see there is an obvious dispersion between SC VWAP & ECI VWAP using both IQfeed & SC data, and an even greater dispersion when using IQ feed data. What's interesting though is that there's a strong correlation between ECI Vwap based on both IQ feed & SC data. - See attachment- Dev Band Comparison *In all examples SC VWAP & ECI Vwap are based on underlying data.
