Hello, I have a Python script that reads real-time prices from Sierra Chart data files and calculates entry/exit signals for a 2-leg spread (ZFU26 + ZNU26). I need to connect this script to Sierra Chart to execute orders automatically. What I tried: DTC Protocol Server: Python connects successfully to port 11099, heartbeat is sent and acknowledged, but SUBMIT_ORDER messages are never executed. No orders appear. Trading System Based on Alert Condition: tried FILE() formula but get #SYNTAX! error Spreadsheet System for Trading: cannot link external CSV My question: What is the recommended way to have an external script trigger orders in Sierra Chart? Is DTC supposed to work with JSON? Or is ACSIL (C++) the only way? Thank you. |

You definitely can use the DTC Protocol server and connect a DTC Protocol client and submit orders through it. If you have an issue like this: but SUBMIT_ORDER messages are never executed. No orders appear.
There must be some issue with the encoding. Yes JSON encoding can be used. Make sure each message is separated with a null character.
