IMPORTANT NOTES:

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

Update: eSignal OnDemand is now 3rd party application compatible, so you can use it with AmiBroker, but you don't receive any streaming RealTime quotes, but only historical (via backfill). 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

Extended historical data was available only to eSignal own application, not to 3rd party applications and only recently this has changed. We are working on updating the plugin to support this recent change in the future.
