Re: [amibroker] Yahoo Historical - Inaccurate Data

Hello,

I don't agree.

If you are using Quotes Plus and QP2 plugin for AmiBroker you already have
full accurracy of 7 significant digits when it comes to split adjusted data.

The same for other data sources driven directly via dedicated plugin.

The number of decimal places are relevant only if data are fed via
ASCII files that have precision limited to 2 decimal places (yahoo downloads for example)
