Missing history or gaps in the chart in Quantower

What is causing it

How much history you get is determined by the connected provider, not by the platform, and some connections supply live data only.

Why this happens

Historical data is requested from the provider on the connection the chart is bound to. What you receive is whatever that provider is willing and able to serve, which varies enormously between vendors.

This is why running several connections is useful. You can chart from a provider with deep history while routing orders through your broker.

The fix, step by step

1. Check how much history the chart is set to load, since a low setting looks identical to missing data.
2. Check whether the connection you are using supplies historical data at all, as some order-routing integrations do not.
3. If you have more than one connection, compare the same instrument on each, because one may have far deeper history.
4. Check whether the gap corresponds to a session break, a holiday or a period the provider does not cover.
5. Reload the chart so it requests the range again, and give it time on a long history request.
6. For tick-based or volume-based charts, expect much less history than for time-based ones.

How to confirm it is fixed

The chart shows continuous bars across the period you need, and spot checks against another source agree.

Stopping it happening again

Know which of your connections is the good historical source and bind analysis charts to it deliberately.
