  | Allows you to enter two smoothed sma periods and it will then     |
  | show you at Which point they crossed over. It is more usful on    |
  | the shorter periods that get obscured by the bars / candlesticks  |
  | and when the zoom level is out. Also allows you then to remove    |
  | the emas from the chart. (smas are initially set at 9 and 18)     |
