Notes

Market Orders

Market orders are not supported.

You can set a very low price for sell order and very high for buy order.
You still have to ensure the price respects the tick size also set the order type to IOC so in the UI,
when a user places a market order we allow a maximum slippage from mid price and calculate the price based on that.
This is a slippage protection mechanism for the user
