"Not enough data available" to plot a chart

There was a few ticker names that was changed on Oslo stock exchange recently, and when I try to download data with this new ticker names from finance.yahoo, Amibroker says that it's "Not enough data available" to plot a chart. It needs at least 3 bars.

Not a big deal, just curious, why does Amibroker need at least 3 data bars to plot a chart?

All good things come in threes...

Couldn't resists.



  1. with SINGLE data point, there would be only DOT, in the middle, not any chart. Also there is impossible to calculate change (from previous bar/day).
  2. with TWO data points the "chart" would be just straight line and similarly useless
  3. THREE data points is minimum to have something that resembles actual "chart"
