Hello all.

I am interested in finding an accurate database of buy/sell records for OTC stocks that are available in at least 15 minute increments.

I am aware there is an ample amount of sources for daily information, but I am more concerned with being able to back-track stock activity down to a focus of 15 minute increments over a one day period.

Ideally, I would like to have access to a database or service that lists buy and sell amounts individually for a single stock rather than a total volume for the 15 minute periods.

If anyone can point me in the direction of such a service I would be very grateful.

Thanks
