Summary
The post is a technical query about data latency when using Interactive Brokers' (IBKR) Client Gateway API to fetch 1-minute OHLCV data.
The author's thesis is that the data is delayed (available at the 5th second of the next minute) and inquires if the TWS API or raw tick data would provide faster, more granular data for building custom bars.
Quality assessment: Noise. This is a platform-specific technical implementation question with no fundamental or market analysis.

I am subscribed to market data and currently using IBKR client gateway API to fetch 1 minute OHLCV data of stocks. It is working fine but I feel it is a little slower as IBKR makes the bar ready at 5th second of every minute. For e.g. if I call at it at 09:32:04 to fetch data of 09:31 minute then it won't be available. The earliest it is available is on 09:32:05.
I was thinking of using TWS API, will it be faster? Or may be I can use tick data from TWS API (if that is available) and build my own 1 minute bars?
