Round current price to closest(up or down) round number (00,25,50,75)

[emches]

Hello,

I am trying to figure out how to get the current price (DAX/GER30 with 2 decimals i.e 12263.71) and convert it to the next closest round number up/or down that ends in 00,25,50 or 75 -> 12275.00

I am trying with:

bidAsInt = MathFloor((Bid/Point)/100);

But this only returns 12263. Scratching my head now on how to get this rounded up to -> 12275.00 or down to -> 12250.00

Any help is greatly appreciated, thank you.

Seems I got it working with the part of the following code

   double step = 25;
   double pricerounded = DoubleToString(step * round(Bid / step),2);

DoubleToString returns a string. You can't assign that to a double if you used strict. Always use strict. Fixing the warnings will save you hours of debugging.

I've changed it and will keep this in mind for the future. Thanks for pointing it out.
