For system developers, one big problem w/E Signal is that they don't offer a meaningful amount of tick data in continuous format or any other.
Many traders use range, volume or tick bars in their systems and these must be build from tick data and while Trade Station offers six months of historical tick data I don't know of any vendor that offers a year of tick data and the little bit offered by E Signal is useless for systems development.
