Eliminating Bad Ticks
There are two methods for doing this. Both are pretty simple and straightforward. There is the manual method documented below. There is also an automated method: right-click in chart and choose "Scrub Data". Start with a light scrub and see if that solves the problem. If not, you can either try a heavier scrub or the manual method below. There is a button on the chart toolbar labeled "Edit/Delete Bar/Tick Data" (7th from bottom on right column). It's the black candle with the red X through it.
