[amibroker] Handling bad ticks with backfill



PureBytes Links

Trading Reference Links

Hello,

I am constantly getting bad ticks in realtime from eSignal on ETFs  
that I watch such as SPY and IWM.  eSignal corrects them right away,  
usually within one bar.  However, AB keeps the  momentary bad H or L  
value forever on that bar.  I fix these right now by doing a lot of  
forced backfills.  However, I have to realize that it must be a bad  
tick, and the backfills take a very long time.  I really only need a  
back fill of a few bars --and I would like to be able to do it  
automatically.

How do other people handle this problem?

Thanks,
Dennis
