  Hello,

   

  I have PRT coupled with IG. Am I the only one which have all wrong % variation calculated for stocks?  It ‘s like this since I have PRT, but now It’s really becoming a problem for me.

   

  Exemple today: Soitec (french stock) is shown with around +6% gain, while the stock is actually gaining +11%…For market understanding, it can be very misleading….

  Ok sorry Soitec exemple was wrong, I was mislead by the calculation of boursorama, which appears to have trouble today. Anyway, I see from where the problem is coming. The closing price of the day before in PRT is the last quote at 17h39, before the auction setting the closing price. So the reference price isn’t correct.

  Are you certain / have you checked that the time from which the increase is measured is the same in both cases?

  Maybe the 11% gain is from market close yesterday and the 6% gain is from midnight / open of a new day on IG’s data??
