I assume you saw my similar thread here: Commercial ACSIL study with local desktop-app dependency From reading the CME data licensing for a normal, non-professional retail user, my understanding of the situation is: **FORBIDDEN OUTSIDE OF SIERRA/ACSIL ** - Any live CME data (last traded price, bid/ask, etc.) - Any data that could be used to derive live data (e.g. live position PnL) - Automated/Semi-automated/Manual order commands that open, close or amend orders/positions **ALLOWED OUTSIDE OF SIERRA/ACSIL** - Order fill information (quantity, and price of transaction) - Current position Size - Calculations based on that static information sent to Sierra/ACSIL So an external app is allowed to ask for the fills and current position because that is static 'account state data', but you can't be accessing live data or any data that allows you to derive live data, and you cannot be issuing orders (manually or automated) from it. So keep the price data and orders within Sierra/ACSIL, but I believe one *can* use position data and order fills externally. I trust Sierra will correct me here if this is wrong. |
