Hello,

Yes, it is technically possible using AddToComposite, even now, but... I see no point in doing so because

a) you would need to keep this open all the time to collect data and if your connection fails you will get data hole that you could not fix

b) the length of history obtained this way will be small (equal to number of days you are running such a formula).

Hi Tomasz,

Is there any way to put the bid/ask data into an array to chart in real time?? Could the static arrays you mentioned to Dennis be useful in this scenario...??

Cheers James.

The main problem with historical bid/ask is that data vendors offer it
rarely (most often only "trade" ticks are available as backfill).
Even if they do, bid/ask comes ONLY in "tick" historical data set, and this means
that backfill is limited to few days at most (eSignal for example gives just 10 days of tick data)

Lack of longer data means that the data is practically useless for
long-term analysis.
