IMPORTANT NOTES:

1. You need regular eSignal Real Time subscription to work with any 3rd party software, including AmiBroker.

eSignal On-Demand does not work with any 3rd party program.

It is eSignal decision and policy that they do NOT suport ANY 3rd party application with their "on demand" product. See feature table and the footnote at:
http://www.esignal.com/ondemand/default.aspx

Quote:

"Please note: eSignal OnDemand data is not available for use with third party software applications. OnDemand does not support DDE, QLink or EFS third party add-on studies. Also, certain exchanges that charge for or do not offer delayed data are excluded, as well as all news services. Tick data is also not available."

2. Limitation on historical data access during peak hours

During the first and last trading hour when the US stock market opens, some limitation to the amount of historical data you can download is imposed.

If you expected to load a lot of historical data, especially tick data, then it is better to do that before market open.

3. Extended historical data option does not work with 3rd party applications

eSignal has not added this option to their API, thus 3rd party applications cannot access those extra historical minute data even if you can see them within eSignal's own software.
