Operation Overview This market maker works on the following principles:
The market maker tracks the last bidVolume and askVolume of the quoted instrument to determine where to start quoting. If the buying orders are greater than selling orders (here volume) price will likely to increace gradually. so bot will place sell order to overcome the selling orders, and so is vice verse. The prices will be predicated on current price as well as lowest selling price in market.
Based on parameters set by the user, the bot creates a descriptions of orders it would like to place. If settings.MAINTAIN_SPREADS is set, the bot will start inside the current spread and work outwards. Otherwise, spread is determined by interval calculations. If the user specifies position limits, these are checked. If the current position is beyond a limit, the bot stops quoting that side of the market. These order descriptors are compared with what the bot has currently placed in the market. If an existing order can be amended to the desired value, it is amended. Otherwise, a new order is created. Extra orders are canceled. The bot then prints details of contracts traded, pending orders, delta and total delta. Simplified Output The following is some of what you can expect when running this bo
