Take a look at the website Kayak.com and use the "3 days before/after" to search. Note there is only one airline that flies between Eindhoven and Budapest.
See the image. You can click the days to find the lowest price combination for trips originating from Eindhoven.
Also try trips originating from Budapest to come the other direction... they may be priced differently.
Finally, plan on making a lot of these trips and see what frequent flyer privileges you can get with Wizz air... for further cost optimization.

Wizz Air does not have a frequent flier programme but it does have a Wizz Discount Club which seems to be just what you need: an annual β¬29.99 gives you a β¬10 discount on ticket fares with the following conditions:
Discount is available on all fares from β¬19.99. Discounts are not available for and excluding flights operated by Wizz Air Ukraine. Fares include taxes, non optional charges, and one small cabin bag (42x32x25cm), but exclude administration fee.
Also, Skyscanner is way better than Kayak for this: it can show a whole month.
