I've reached the point in my system design efforts where I need input from a very capable statistician. My question is whether I should seek one within the trading community or from outside (e.g., academia). The argument for finding one inside the trading community is that the person will already understand the markets and the nature of market data. The argument against is that the person may bring a significant amount of bias to the effort based on their own research/strategies. The argument for finding one outside the community is a lack of the aforementioned bias. The argument against is finding someone who will be interested enough in the markets to bring sufficient energy to the task. Any insights are appreciated. Thanks.
