Posting this question in the prop firm section because I know a lot of firms use sterling. Question is how do you get sterling to calculate a negative fee for adding liquidity and a rebate for removing liquidity, eg. Edga. My firm couldn't give me any info, I looked through the manual, even called up sterling- they said it isn't possible. I have a hard time believing that. Any help is appreciated. Especially if some could send me their fee file. Thanks
