sweet and sour sauce restaurant style

I am looking for a certain type of sweet and sour sauce. many restaurants make it. it is bright red and not to thick and not to thin and it is used for dipping your egg rolls or won tons in it. as well as other food. i hope someone knows how they make it . and it don’t have catsup in it. thank you all for your help.

thank you for those versions but i don’t think any of those are it. and there is no catsup in the sauce i am looking for. and wow you know a lot of recipes i bet you are a wonderful cook. thank you
