If you really do HFT trading I'd be more curious to know whether your algorithms can scale up and remain profitable with more exposure. If that were the case acquiring more capital shouldn't really be an issue for you.
Get your track record audited and then shop yourself to Chicago prop firms. If things look robust, you should have no problem getting capital on a profit split.
It would seem that anyone who could consistently arbitrage a currency OR synthetically front run transactions would be able to capture a great deal of value extremely quickly. Further, they should have an easily identifiable and intelligible record of success. Have a pitch deck ready if you don't already.
Either one should either generate the capital you need, get your system bought by a big player, or get you hired with a big salary by a big player.
