Just watch the differences in realized fills between the broker and strategy on chart. In AA mode you see the differences with MC engine calculation. It is a known behavior for MultiCharts.
Make it is possible, where all the signals on chart,
everytime when there is a new arrow on chart shown, that this signal
with the amount of units shown above the arrow, is sent to broker as market order.
So there are only market orders, without the shortcomings of any stop and limit orders at different brokers which have to be modified, changed, deleted etc.

It should be possible that one apply his strategies on charts in a workspace but does not turn autotrade on, because then MC engine calculation takes place. So there must be one another chart for the global variables to pass the chart signals as market orders to the broker.

Thank you.
