Quote from bwolinsky:
E-signal and all the data providers do a disservice to their members not keeping 5 years of tick data on hand. They should at least have 2 years, but they're lazy and don't want to store it.
Quote from zgtrader:
Anyone know E-Signal's back fill for tick data? It was 10 days but I would hope its been upgraded since.
Quote from eSignal Support:
We have up to 40 days of ticks with our add-on service level.
