Open trade out side chart

[ipul]

Hello,
I tried to make a very simple EA based on Stochastic Indicator Stochastic that suppose to open BUY when Stochastic value cross above 10 and open SELL when Stochastic value cross below 90.
When I tested, I found strange things some position were opened beyond the chart as shown in below picture !Screen shot image url).
In earlier timeline of the chart, position were not taken although conditions were met and no open order.
May I know what did I do wrong?
Thank you

@ipul You need to use a 'once par bar' block on top of both trees to avoid multiple executions per crossing.
