Message received contains unexpected values for some fields.

thomas.abraham

some messages received from Refinitiv Real Time Optimized Websocket API have unexpected values for some fields.

Example:

"DSPLY_NMLL": "\u001b[0` \u001b[31b",

"CTBTR_1LL": "\u001b[0`<CALCS_EXPLAINED>\u001b[17` \u001b[4b"

What is this means and how can I decode this?

Thanks,

It is a partial field update, as mentioned in this How to retrieve page-based data using Refinitiv Tick History REST API article.

For exmple: "\u001b[0` \u001b[31b"

"\u001b[0`" represents an intra-field positioning sequence.

• "\u001b[" = <CSI>
• "0" = an ASCII numeric string representing the cursor offset position
• "` = <HPA>

" \u001b[31b" represents a character repetition.

• " " = the character to be repeated (a white space)
• "001b[" = <CSI>
• "31" = an ASCII numeric string representing the number of times to repeat the character
• "b" = <REP>

You need to apply these partial field updates to the previously retrieved data of those fields.
