The bot actively quotes on one quoting exchange with the use of the limit orders, adding the predefined spread to the price obtained from the hedging exchange. In case the order is filled, the bot hedges on the hedging exchange with the use of the market order. This strategy is much faster and allows for scraping spreads as small as 0.01%. Implementation required major changes in the architecture of the system. Also much more enhanced integration of the streaming exchange interfaces – i.e. private streaming channels with trade & order updates.
