Dear all fellows, Could anybody tell if you have the experience to be blacklisted by any broker simply because you are consistently profitable (either discretionary or through system trading) ? What are the actions for the blacklisted candidates ? Do not accept any orders from them ? Suspend the account ? If so, can you disclose which are they ? Since the number of brokers which expose the API for order execution are so limited, anybody experienced that it keeps being blacklisted until you can longer use an automated solution ? For the brokers which act against certain traders individually. Can they make the "spikes", that is, make an extra-ordinary quote which force close the individually client's positions.. but that spike only appear on that client's chart. Is that possible ? Seems all brokers dont offset all clients' trades through the market ? Any exception ? Thanks so much !!
