You are missing a clause in your translation for the Trade Station part: AND buystop < buystop [ 1day day ago]
Also, rather than recalculating the offset array each time, it is better to store the value in an intermediate variable and only do the calculation once.
e.g.
avgPrice1DayAgo = Ref(averagePrice, -1);
notWideningBuyStop = IIf(averagePrice >= avgPrice1DayAgo && ...)
For plotting, you can use a number of pre-defined shapes in conjunction with the PlotShapes function. There are a number of posts in the User's Knowledge Base on this:
