Hello, everyone I have a strategy that works optimum with a fixed spread however the broker providing this service does not have historical tick data availiable from the dealing desk servers, therefore the best historical data I have is the spot market data from Dukascopy bank. Of course it won't be 100% accurate but I was just wondering the mechanics of how market maker fixed/custom spreads differ from the spot market i.e. is a tight fixed spread within the spot quotes or can it travel outside of the spot bid/ask? Kind of a tricky and varied question but anything that can help is welcome.
I believe they take average spread and add some fat premium to it. Check Hotforex they offer fixed spread account too.
