| 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) |
