Because I have a real-time data feed.

By data lag, do you mean network latency from the exchange servers to your computer? If so, do not worry about it too much unless you are in a location with extremely spotty internet access. Certainly, latency arbitrage would not even be a game you could begin to play in even if you had a fast fiber optic connection.

Unless you are trading millions of contracts/shares, this "data lag" you speak of does not affect you.

People can you please answer the question ?

Data lag means how much time it takes to see a trade or bid/ask change on your screen after it happened in the exchange.

Human reaction time is much longer than any data lag. HFT is the game to play it. Even you know the actual data lag there’s nothing you can do as a human.
