Hi Eugene and Cone, i run some backtests for trading... but there are some bugs, because some market prices are not correct and the open positions are too many (20% pos. size) . And in my second stragegie, the open symbols are wrong (from yesterday to today should be no changes...). Could you please help as soon as possible. Two pictures of the problem below.
Thank you very much!
Marko

Hi Marko,
What is the data provider?
Are you seeing the zero price on a chart of affected symbols?
How can we reproduce this, step by step?

Hi Marko,
try to use a different data provider (e.g. Yahoo, Q-Data, MorningStar) and do the backtesting again! I encountered the same problem, since WealthData gives wrong quotations for some stocks, today.
Hope this helps!

WealthData is an end-of-day provider. You shouldn't even be able to see data for today's bar in Wealth-Lab 7/8 until the market session closes. If somehow you did, how did you?
i just jused Wealthlab-Data's . And of course I just like the end of day data's. But something is wrong today.
Thanks for the idea to use Datas from yahoo as a special exception.

Okay, we think an update process didn't shut down yesterday and was updating symbols premarket today. The data already self-corrected, but won't necessarily correct itself on your machine.
You can probably fix this 2 ways.
1. In Preferences > Data check the box to "Allow Data Corrections from Historical Providers"
2. Periodically (and now), I'd recommend refreshing Wealth-Data completely to make sure you're getting all the corrections. Data Manager > Historical Provider > right click Wealth-Data and Delete Local Files.
