How to effectively describe your custom indicator project.

Please use the following format to submit your project request.



First, summarize the indicator you want to build. For example, this indicator will plot a green up arrow and play a sound alert when current Close price is below EMA(30) and ADX cross above value 10. And it should plot a red down arrow and play a sound alert when current Close price is above EMA(30) and ADX cross below value 50.
  


Second, list all the inputs you need for the indicator.

Input of your customized script is different from the platform's built-in setting parameters.

The following pic shows all the inputs from a custom indicator.



For example, if your custom indicator need to use EMA and ADX.

Please list the input name and description in the following manner.

1. length, the lenght input of EMA used in the indicator, use 30 as default.
2. period, the period input of ADX used in the indicator, use 14 as default.
3. ADX upper level,  a number used to check if ADX cross below it, use 50 as default.
4. ADX lower level,  a number used to check if ADX cross above it, use 10 as default.
5. Alert, switch to turn on/off the sound alert.

Third, please list everything the indicator should do.
Please consider the following as an example.

1. plot a green up arrow and play a sound alert when current Close price is below EMA(length) and ADX(period) cross above ADX lower level. 
2. plot a red down arrow and play a sound alert when current Close price is above EMA(length) and ADX(period) cross below ADX upper level.

I know that your indicator could be more complex than the example above, but the two most important parts for any indicator are the input and plot, as long as you submit those two parts by the same structure above, it will help me to understand your request completely.
