HOLD THE PHONE!!! Keep it simple stupid. I am not being disrespectful, its a saying... Its the KISS method of teaching.
Here is my stupid question; Are you saying i place a sell order on BITSHARES to sell steem at a particular price and it checks all the other exchanges for the best price and then fills it?
If the order you've placed would fill on any of the other exchanges I'm tied into then yes your order will be filled automatically.
So if I placing an order in bitshares/openledger it stay until your bot find in any other exchange match and you bot make trade on both sides?
