HFT having a lot of volume is irrelevant, what matters for Julia to be prevalent, is to have a lot of analysts use the toolset. You should measure the amount of analysts working in HFT vs those not working in HFT. Furthermore - HFT is perhaps the worst case for Julia, since the implementation will always be in low level languages. Julia's speedup is only useful for research in HFT.
