API

class stakemachine.strategies.echo.Echo(*args, **kwargs)
error(*args, **kwargs)

What to do on an error

print_UpdateCallOrder(i)

Is called when a call order for a market pegged asset is updated

A developer may want to filter those to identify own orders.

Parameters:i (bitshares.price.CallOrder) – Call order details
print_accountUpdate(i)

This method is called when the bot’s account name receives any update. This includes anything that changes 2.6.xxxx, e.g., any operation that affects your account.

print_marketUpdate(i)

Is called when Something happens in your market.

This method is actually called by the backend and is dispatched to onOrderMatched, onOrderPlaced and onUpdateCallOrder.

Parameters:i (object) – Can be instance of FilledOrder, Order, or CallOrder
print_newBlock(i)

Is called when a block is received

Parameters:i (str) – The hash of the block

Note

Unfortunately, it is currently not possible to identify the block number for i alone. If you need to know the most recent block number, you need to use bitshares.blockchain.Blockchain

print_orderMatched(i)

Is called when an order in the market is matched

A developer may want to filter those to identify own orders.

Parameters:i (bitshares.price.FilledOrder) – Filled order details
print_orderPlaced(i)

Is called when a new order in the market is placed

A developer may want to filter those to identify own orders.
