Request for QUIK connector refinement - transfer of the "Execution condition: Passive only" (Post-Only) parameter

Hello!

I'm writing regarding a question I've already raised with your support team. It concerns connecting ATAS to QUIK (broker KIT Finance).

QUIK allows you to place orders with the "Post-Only" execution condition. This allows traders to act as makers and avoid paying the 0.03% exchange commission on each trade. For active traders, this represents a significant savings: with a monthly turnover of 10 million rubles, losses amount to 3,000 rubles, or 36,000 rubles per year.

However, as your employee Alexander Khayosh confirmed, when orders are sent from ATAS, the Post-Only flag is not transmitted to QUIK—all orders are processed as regular limit or market orders. As a result, when a limit order is executed immediately, I become a taker and pay a higher commission, even if Post-Only mode is enabled in ATAS.

The ATAS documentation specifies the IOrderOptionPostOnly interface with the PostOnly flag. This means that the platform architecturally supports this. The problem lies specifically with the QUIK connector, which does not transmit this parameter to the transaction.

I request that you consider improving the QUIK connector so that the Post-Only flag is correctly transmitted to QUIK in the "Execution Condition" parameter = "Passive Only" (or BOOK_OR_CANCEL in the universal transaction format).

This is critical for traders who use ATAS for analysis but are forced to submit orders manually in QUIK simply to save on exchange fees. Without this improvement, ATAS is less cost-effective than submitting orders manually in QUIK.

Please advise:

1. Is it possible to implement this feature in the QUIK connector?

2. If so, when can it be included in the update? 3. If implementation is not planned, what are the alternative ways to convey the Post-Only feature in QUIK?

I am happy to provide additional technical details if this will aid the assessment.

Sincerely,
