After running an End of Day OmniScan, I have several stocks in my database that show negative price data. It usually starts around the year 2007-2009 time frame. Is there away to correct this problem. I have RELOADED STOCK DATA and used REPAIR DATA BASED FUNCTIONS, neither of these function have helped.

Yes, I often get that too.

The data really needs to be scrubbed.

Check out this thread: http://www.omnitrader.com/currentclients/otforum/thread-view.asp?threadid=8938

I'm guessing that you have "Automatic Dividend Adjustment" selected in Easy Data Settings. It should not be selected.

Thanks for the help, after unchecking the selection for Automatic Dividend Adjustment,it does correct the negative chart data. However, unchecking that option causes other charts to lose the Vote Line and Strategies Signals. Look at Ford (F) and General Motors (GM) before with the Automatic Dividend checked and after with it unchecked after you Reload the data.

Any thoughts on how this can be corrected.

Personally, I don't consider that a problem to be corrected. The price sequence has changed, which affects many indicators. Some indicators, e.g. EMA, are affected by changes in data many many periods in the past.

So, you have to decide whether you want data "adjusted" for dividends, or not. Using data "adjusted" for dividends, will result in some stocks with negative values. Personally, I don't find that useful.

Thanks for the comments and you are right. I have come to learn and appreciate the crazy quirks of OT and have learn how to deal with them. I am always a little surprised to see coding flaws that still exist having been a user since around 2004, customer number 7374. I have had a chance to deal with the good, bad and ugly. While there are many systems who can present chart data without negative price data, none can provide a system that has allow me to developed back tested strategies that are highly and consistently profitable.
