  event AddIndex(uint256 _indexNo, bool _isOpen, uint256 _initIndexPrice);
  event UpdateIndex(uint256 _indexNo, bool _isOpen);

}

Events

• UpdateIndex(uint256 _indexNo, bool _isOpen) The index status is on or off.

• AddIndex(uint256 _indexNo, bool _isOpen,uint256 _initIndexPrice) add new index.

• SetOracleTimeClock(address _newOracleAddr, uint256 oracleUpdateAt) Execute the new orcale，and it can be enabled after 7 days.

• ExecuteOracleTimeClock(address new_oracle) Switch to the new oracle.

Methods(Read Contract)

1. Batch Index Price

function batchIndexPrice(uint256[] calldata _indexNoArr) external view returns (uint256[] memory _prices)

batch get index price

param	type	description
_indexNoArr	uint256[]	indexNo array

return	type	description
_prices	uint256[]	price array

2. Get Index Price

function getIndexPrice(uint256 _indexNo) public view returns (uint256 _indexPrice)

Get index price

return	type	description
_price	uint256	price

3. Index Length

function indexLength() external view returns (uint256)

Get index array length

param	type	description
length	uint256	index length

4. Is Index Open

function isIndexOpen(uint256 _indexNo) external view returns (bool)

isset index is open

param	type	description
indexNo	uint256	indexNo

return	type	description
isOpen	bool	index is open

5. getIndex

function getIndex(uint256 _indexNo) external view returns ( address[] memory tokens, uint8[] memory weights, uint256[] memory circleSupply, uint256 k, bool isOpen )

get Index tokens and weight,circleSupply

param	type	description
indexNo	uint256	indexNo

return	type	description
tokens	address[]	index tokens
weights	uint256[]	weight of tokens
circleSupply	uint256[]	circly supply of tokens
isOpen	bool	index open status
