Hi,
Am trying to run a simple trade script using Zorro and IB TWS against LSE stock ULVR using symbol "ULVR-STK-SMART/-GBP".
It seems to recognise the symbol however no matter what bar period or lookback I use Zorro generates the following messages:

Start Asset ULVR - ULVR history unavailable!
Error 055: No bars generated

TWS shows the data fine and if I run the same script against "AMZN-STK-SMART-USD" or other exchanges like "CBA-STK-SMART/-AUD" it works.
Thanks.
