Tick intervals require eligible plan access and a supported chart context. Check the official availability rules and do not assume that a real-time exchange subscription alone enables them.
What you may be seeing
- The tick interval options do not appear
- A custom tick interval is rejected
- The chart supports seconds but not ticks
Most likely causes
- The current plan does not include tick-based intervals
- The symbol or product context does not support the requested tick chart
- A time-based interval is being entered instead of a tick interval
Try this first
- Open the interval selector and look for tick choices
- Confirm the symbol is supported
- Review current official tick-interval availability
- Compare plan access only if tick charts are a required workflow feature
If that didn’t fix it
- Use seconds intervals for time-based granularity
- Use a supported built-in tick interval
- Validate the strategy on standard time charts before adding tick-specific logic
Verify the fix
A supported tick interval opens and forms bars from market updates as expected.
Why this happens
Tick intervals require eligible plan access and a supported chart context. Check the official availability rules and do not assume that a real-time exchange subscription alone enables them.
Tick charts create bars from a number of trades or updates rather than elapsed time. They are separate from seconds intervals and can have different historical and feature limitations.
