How can I manually correct the backtesting cache?
How can I manually correct the backtesting cache?

Hi,
On April 17, at 00:09 UTC UK100 has a low of 2375.6, and then it returned to its normal value around 7300 at 1:04.
This obviously messes up my backtesting.
I found the tick cache file in my AppData folder and deleted it, hoping it would re-download a corrected version but no dice.
How can I edit this manually?
Thanks.

Another rogue bar, on XAUUSD:
Gold spikes down to 1245 to 692 at 5:32am June 4, 2014, (UTC-6, so maybe 11:32 UTC.)

Hi Jared
I picked up the same kind of problem on the UK100 back in November last year. I approached IC Markets directly and, after a few mails explaining what the problem actually was and some false fixes, eventually they fixed the data.
So thats an option. Good luck

Thanks, Rhett, I will keep that in mind.
It might be good for Spotware (or brokers) to have some sort of automatic rogue bar detection feature, ideally for live data (filter out bad data in the first place, or maybe it is tiny LP's with a nearly empty order book getting switched on before the rest of the LP's?) but at least so it fixes up the backtest data within a few days of it happening.

Dear jaredthirsk,
Could you please let us know the broker so that we can check the historical data and fix any issue if exists?
Best Regards,
