Missing data for 9th October – Norgate/AmiBroker?

[Anonymous]

Anyone have any issues with data today missing. After running my scan an unusually high number of setups. Looked into a lot of setups and saw data only for the 6th as last bar – but most had 9th as last bar?

Reloaded data and restarted and did maintenance on AMiBroker and problem persisted.

A few examples of missing tickers TSLA, NCSM, VERI among others (have found about 50 in total)

Have logged a query with Norgate but wanting to see if anyone else had issues.

Thanks all – sent error logs and examples to Norgate, they saw errors but didn’t know how this occurred. On their suggestion reinstalled all historic data from scratch, seems to be ok now.

One thing this has taught me – as it has happened to me before – it to always be suspicious of anything that seems out of place. Last time it was certain months in backtests giving very different results that alerted me, this time an excessive number of setups (it was high anyway, but I just started checking random tickers and found the error)

The concerning thing is that there was no other sign of anything wrong, or any indication the data was corrupt!

Your gut instinct can lead you astray when making a decision about whether to buy or sell a stock, but rarely leads you astray if something seems a bit strange. Good to follow it up always.
