Events

The websocket endpoint of BitShares has notifications that are subscribed to and dispatched by dexbot. This uses python’s native Events. The following events are available in your strategies and depend on the configuration of your bot/strategy:

• onOrderMatched: Called when orders in your market are matched
• onOrderPlaced: Called when a new order in your market is placed
• onUpdateCallOrder: Called if one of the assets in your market is a market-pegged asset and someone updates his call position
• onMarketUpdate: Called whenever something happens in your market (includes matched orders, placed orders and call order updates!)
• ontick: Called when a new block is received
• onAccount: Called when your account’s statistics is updated (changes to 2.6.xxxx with xxxx being your account id number)
• error_ontick: Is called when an error happend when processing ontick
• error_onMarketUpdate: Is called when an error happend when processing onMarketUpdate
• error_onAccount: Is called when an error happend when processing onAccount

    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)

        """ set call backs for events
