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