This is a rare message that appears if there have been no new prices for some time or the last price available could no longer be treated as the current market price.
Because the price is no longer available, your order is not able to be executed.
Off quotes can occur at times of thin liquidity. For example, shortly after the start of the new trading week on Sunday or before the market closure on Friday.
To minimise the number of Off quotes you receive, you could:
- Try to avoid trading during periods of reduced liquidity
- Avoid trading low liquidity instruments
