It would seem odd that it has not moved the trailing stop in that image. It does not show that you have two positions open on the same market in the image. If you do then it would be interesting to see where the average position price is compared to where the trailing stop is. If it is 144 pips from the average position price of two positions then you might be correct and the broker is applying a trailing stop to your average position.
In the past forum members have not had much joy with the built in TRAILING function and have generally hard coded in their own trailing stops. Just check at the close of each bar if price has closed or reached a new high/low that means the stop should be moved and adjust the stop value accordingly. Using MTF it should be possible to do this every second so that it is a truly fast adjusting trailing stop although this does massively reduce your available amount of back test data.
