# Watchlist Data Limitations

It is important to mention that our real time market data is not tick-by-tick, meaning you will not obtain every single price movement happening in the market. Instead, real time data is given as snapshots generated at a fixed given pace:

| Product                    | Frequency |
| -------------------------- | --------- |
| Stocks, Futures and others | 250 ms    |
| US Options                 | 100 ms    |
| FX pairs                   | 5 ms      |
