(MT4) - Get OnChartEvent to work in Tester to detect objects

[samsgtw]

I have written an ea that detects when a trendline is placed on the chart by an indicator. When the EA detects a new line has been placed on the chart it executes a trade function.
However i have been trying to backtest in the tester and noticed that my OnChartEvent function will not work and therefore i cannot detect the creation of a new line.
Is there any way to get this to work.
P.S. i Have found a few forum posts about using buttons in the tester and working around the issue but i cannot find anything for chart objects

Code your OnTick to check for them.
