MultiCharts: Trading Software for Automated Trading and Backtesting

I have a problem where an indicator (very simple MA) I use with no problems on many. many currency pairs but doesn't work properly on YEN crosses.

The problem is that when I plot the MA but then change the size of the chart window or the price scaling the position of the indicator moves around all over the place. I have attached 4 screen shots to show what I mean. You will see how at different chart sizes the indicator is in very different location in relation to price.

Any ideas as to why that is the case? Better still, any suggestions for a fix? All chart settings are the same for all pairs (that was the first thing I checked).

Note where price and the MA are relative to each other on these two screen shots.

Please go to the Format Study window, Scalling tab and make sure that the Scaling Type is Same as Symbol.
