Why is their sometimes a difference between prices on ACM’s charts and the prices provided in the Live Trading windows?
Unlike other brokers, ACM’s charting data is provided by an independent 3rd party. The prices on the charts do not show all the highs and lows of the markets and can loosely be considered the average price that ACM is able to offer. The ACM graphs do not show the prevailing spread at a given time, while showing the highest Bid and lowest Offer.
