MarketBookAdd returns 4901 and SYMBOL_TICKS_BOOKDEPTH is 0, but manual DOM window opens on MT5

Hello, I would like clarification on MQL5's market depth behavior. I am developing an expert advisor that reads market depth data using MarketBookAdd() and MarketBookGet(). The same diagnostic EA works correctly with other brokers, but it doesn't work on my IC Markets MT5 live account. environment
