Improve the order method to avoid switching

It is very inconvenient to use this place in the order panel, and you have to manually switch between market and limit every time, which is inconvenient, directly a box, the default is market, and if I change it to a number, it is directly to place an order with this number limit. After the order is completed, the market will be restored directly, and this place can still be improved anyway to avoid manually switching between market and limit
