hi, when I open a chart and set a symbol that doesn't exist in SC, I get a request on the server for MARKET_DATA_REQUEST (type 101). 1. I am also receiving a message of type 109. I looked in the header file and there is no 109 message. I was expecting SC to send me a HISTORICAL_PRICE_DATA_REQUEST but am not getting one. Not sure if I am doing something wrong on the server or perhaps not pressing the right buttons in SC that would cause such a request to be sent or perhaps SC never sends such a request. 2. In short, how do I get SC to send a request a HISTORICAL_PRICE_DATA_REQUEST? |

see below opening chart with "somesymbol2" as the symbol DTC Service: Connecting to the server localhost.

From what we see you should be getting it. We will add more logging to confirm, but we are quite sure s_HistoricalPriceDataRequest is being sent.

that answers half the question so I know that I should be receiving it. Apart from logon response, right now my code just checks the message type - when I receive a complete message I print it. From my end I am seeing that 101 & 109 are being received but I might be missing something. I'll double check on my end. (Regarding your comment, the header file I got from Github doesn't have s_HistoricalPriceDataRequest. I am stating this just to confirm that I am looking at the latest header file and that you don't have a more updated one. I am adding structures as I need them right now.) |

In the case that my service supports historical data only (no real time data), when I get the s_MarketDataRequest for a symbol, should I be returning a s_MarketDataReject?

It is not essential, but good practice.

The C++ header file we have contributed does have this data structure: (Regarding your comment, the header file I got from Github doesn't have s_HistoricalPriceDataRequest.

Yes, I am using that to add structures to the c# header file. That and the rythmic bridge are a great source for reference. Reviewing a network capture I did, I can confirm that the historical data request is certainly being sent from SC so its something in my server - you can see this thread closed. |

The Rithmic bridge project that we have posted is older and we have to update it. We will try to put out an update for that today. But nevertheless it should still act as a good source code reference. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.
