We subscribe to Level2 and cache the book in our application. We noticed that sometime we receive CLAER_CACHE and do not receive REFRESH_COMPLETE for a Level2 Market Maker domain. After few minutes we start receiving Updates messages without receiving REFRESH_COMPLETE. Is this an expected behavior, if yes then how do we know that we got the initial book completely. We usually notice this happens for RICs which are subscribed before market open.
We rely on REFRESH_COMPLETE as an indication of completion of book message. Please share if you experienced such behavior, if yes any suggestions/work-arounds.
