Better at side interest than job

Currently a prop day trader (equities) in the trading arm of a HF, algos n stuff, doing fine at it, but was recently asked to try and find ways of using the hedge funds cash in longer term strategies as something to see if possible. Started doing currencies and have become pretty good at predicting a few of them. (holding periods of weeks/months if still going in the right direction - e.g. Japan).

I am strongly considering jumping across if this takes off, but where to and saying so yea, i wasnt ever interested in currencies but it turns out im not bad at them might not sit right at a job interview.

Yes im aware its possible my results are flukes, past performance is no indicator etc., but if you were in my shoes what would you do? Keep working at my day job, ask to do more in the currencies? (we dont really have a currency desk, im sort of starting it).

The sad part is, my own PnL is not influenced by the funds cash signfiicantly. If i use their capital we can offset the costs of trading into some of their transactions, however being able to prove i can do currencies well feels like its potentially more valuable. More importantly, I feel like I get currencies more than I do equities.

To keep the cynics contributions constructive, what would I have to demonstrate in what time frame that this is something I can do, rather than random chance.

Thanks in advance
