  | Allows you to enter two ema 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. (emas are initially set at 5 and 6)              |
