I am trying to use Rithmic data to feed a chart.

I configured data service to DTC Service. Set True to Skip Encoding and Logon requests.

I receive MARKET_DATA_REQUEST SUBSCRIBE and I send back MARKET_DATA_SNAPSHOT and then I start feeding MARKET_DATA_UPDATE_TRADE according to https://www.dtcprotocol.org/index.php?page=doc/DTCMessageDocumentation.php#MarketData

but on the chart I have weird bars. in the beginning they range in -2 - 2 values (instead of real ES prices of 3400 something). And then they change to bars which stretch the whole screen with some huge values like -420000.

DF (data frames?) counter is changing as expected.

I am pretty sure the endianness and values are correct - I checked it byte by byte. The order of fields is according to the document (the link above).

what do I do?

Message example (decimal numbers):


{byte[34]}

There must be something you are doing incorrectly regarding the encoding. What encoding are you using?
