##Events

• Maker(address maker, bool allow) Add new or modify market maker permissions

• MakerDeposit(address payToken,uint256 indexNo,uint8 poolId,address maker, uint256 amount, uint256 fee ) Market makers deposit margin MakerWithdraw(address payToken,uint256 indexNo,uint8 poolId,address maker, uint256 amount) Market makers withdrow margin

Methods(read thmods)

Based on the market maker address to lookup: maker_index

1. Allow Maker

mapping(address => bool) public allowMaker

Whether to run deposite margin

2. Maker

address[] public maker;

Based on maker_index to ger address

node

let address = await contract.maker(maker_index);

3.Rate

uint256 public rate

**The rate of market maker deposits margin **

4. Maker Balance

mapping(uint256 => mapping(uint256 => uint256[16])) public makerBalance

View the balance of single market maker in option pool

param	type	description
index_no	uint256	index_no
maker_index	uint256	maker_index
pool_id	uint8	pool_id

return	type	description
balance	uint256	balance

node

	let balance = await contract.makerBalance(pay_token,index_no,maker_index,pool_id);

5. Order Maker Length

function orderMakerLength( uint256 _orderNo ) external view returns (uint256)

Order maker length

6. Get Order Maker

function getOrderMaker( uint256 _orderNo, uint256 _start) external view returns (uint256[50] memory makerArr, uint256[50] memory makerMargin)

Get order maker

param	type	description
order_no	uint256	order_no
start	uint256	start from

return	type	description
makerArr	uint256[50]	maker_index list
makerMargin	uint256[50]	margin list

7. Pools

function pools(address _payToken, uint256 _indexNo, uint8 _poolId) external view returns (uint256)

Pools balance
