Custom Multi-Timeframe Screener with Alerts

19 may 2021

This is a multi-timeframe screener with alerts. Use this way you can create a screener on indicators using 2 or more timeframes.
In TradingView there is a limit of 40 security function calls. Every timeframe requires another security call so you can screen fewer symbols with any additional timeframe.
In this example, I use 2 timeframes, so the maximum amount of symbols you can scan is 40/2 = 20.
For 3 timeframes - 13, 4tfs - 10, 5tfs - 8 symbols and so on.

In this simplistic example, I require a cross of EMAs on the current timeframe and confirmation that one EMA above/below another from the second timeframe.
Of course, you can create much more complicated functions for this screener.

Params
- higher timeframe
- ema params
- 20 symbol inputs for instruments you want to use in this screener

Alerts
You can create an alert from it easily by selecting the screener name from the list and then selecting "Any alert() function call".
No additional configuration is required, message and alert on close is generated in the code.
You should better change the default name for your alert. Sometimes because of big amount of inputs you might receive an error.
