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.
