The Federal Reserve Bank of Chicago has weighed in on the current state of the financial markets and whether they are fair to investors, Bloomberg reports. In recommendations in a working paper published on Wednesday, the Chicago Fed proposes implementing limits on high-frequency trading firms and incentives to bring more buying and selling into public view.

The working paper, written by John McPartland, a senior professional in the bank’s economic research department, proposes nine measures that it says “would likely restore the perception of fairness and balance to market participants that would be willing to expose their resting orders to market risk for more than fleeting milliseconds.”
