## Posting Prices
|
||
|
|
|
||
|
|
An authorized oraclef for a particular market can post the current price for that market using the `MsgPostPrice` type.
|
||
|
|
|
||
|
|
```go
|
||
|
|
// MsgPostPrice struct representing a posted price message.
|
||
|
|
// Used by oracles to input prices to the pricefeed
|
||
|
|
type MsgPostPrice struct {
|
||
|
|
From sdk.AccAddress `json:"from" yaml:"from"` // client that sent in this address
|
||
|
|
MarketID string `json:"market_id" yaml:"market_id"` // asset code used by exchanges/api
|
||
|
|
Price sdk.Dec `json:"price" yaml:"price"` // price in decimal (max precision 18)
|
||
|
|
Expiry time.Time `json:"expiry" yaml:"expiry"` // expiry time
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
