So how are tick charts drawn?

I want to start trading with Sierra chart but i want to make sure that data is right, and it just doesn't look right. On TradeStation I have drawn a trend line matching the lows of the circled areas. Notice how the price pokes below the trend line in the rectangle? This is a 2000 tick chart with 5 days data with session times 15:30-15:15 Eastern time.

This is an open ecry chart of the same thing. Notice how price breaks the trendline exactly as TradeStation does, although the chart is slightly different.

This is NinjaTrader from another trader, notice how it is identical to TradeStation but very different to Sierra. Why does Ninja match TradeStation precisely, but no matter what settings I change Sierra doesn't want to match any of them?

This is Sierra Chart with infinity demo data feed. Notice how on this chart price barely breaks the trend line. This kind of data difference can affect how I trade and I need the data to be spot on. Why are there differences?

Sorry for the large images, I have a big monitor.

Answer: data feeds are not equal, and almost certainly nothing to do with the platform (except for TradeStation, which forces you to use TradeStation data).
