open price you set must differ from market price by at least 0 points

 
Hi, im setting a pending order in MT4 and got error message: "open price you set must differ from market price by at least 0 points" = the price i´m setting is tens of points away... What I´m missing? thnx L. 
 
You can't set buy stop pending price) closer to the market than the minimum.
  1. The zero means MT4 doesn't know what the minimum is.
  2. The Ask line, per your image, was 75106 but your entry price was 75000. Closer than the minimum, it is below the market.
