charting sw that draws trend lines?

[BuyLowSellHigh]

Is there a charting software that can find & draw various straight trend lines AUTOMATICALLY for you? Preferably one that I can use with IB TWS for for daytrading? I draw them manually with mouse clicks on QT but sometimes I miss some and associated profits. Would be nice to have SW do it for you. However, I would imagine it's not easy to make the SW smart enough to do that properly.

you can draw trend lines with tradelink :

public class MyIdea : ResponseTemplate
{
  MyIndicator myi = new MyIndicator();
 public override void GotTick(Tick k)
 {
      sendchart(myi.Value);
 }
  public MyIdea() {}
}

What's that picture? I don't see any trend line. I am looking for straight lines connecting two or more highs or lows.
