Hi,

 

Can anyone please modify this EMA crossover indicator as below,

 

Currently whenever there is an EMA cross occurs it triggers an email with text "EMA (6) crosses UP SMA (50)".

 

Is it possible to add the value along with the text as below

 

Eg: "EMA (6) crosses UP SMA (50) at 1.3365"

 

 

Below is the code,

| 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) |
