Overview
Finally an Indicator that has alerts/alarms that works with Logarithmic trendlines!
A- This indicator plots a customizable logarithmic (or linear) trendline based on user-defined start/end dates, extending forward to highlight support/resistance.
B- It shows green upward triangles for bullish breakouts and red downward triangles for bearish breakdowns or dots for touches that are not effective crosses of the trendline
C- It is also possible to set alert conditions with custom message for helping to trade the signals above/bellow the trendline


How to Use
1. Apply indicator to chart.
2. Adjust inputs: log/linear, price source, start/end dates, custom prices , label/triangle visibility.
3. Setting -1 for the price source adjusts the trendline automatically to the height of the chart for the specified date based on high, low, close or open of the candle for that date.
4. Watch for triangle signals on bar close.
5. Set alerts for breakouts/breakdowns or touches via TradingView.


Multiple Logarithmic Trendlines are possible!
You can put many logarithmic trendlines in your chart with alerts!, just as many as many alerts your current tradingview plan allows you to.

How to?
- Just use this indicator, get the logaritmic trendline you desire, set the alert, make sure is well set, and after setting the alert draw yourself on tradingview the logarithmic trendline that you are setting the alarm to (a new manual drawing).
- Then modify the settings of your indicator to create a new trendline, the previous one exists even if not visible as long as you have correctly set the alert, and if you did a drawing you can see your previous alert trendline.

Custom Messages on Alerts
- There are different options for the alerts, the one named "Any alert() function call" allows you to put custom messages that could be used on platforms like Wundertrade in order to set and execute automatic trades on buy/sell.
- The other options for the alerts give you fix messages and allows you to decide if get you an alert on a cross over or under or on a touch of the trendline.

Notes
- Signals on confirmed closes (no repainting).
- Designed for log-scaled charts but also works on linear charts.
- Tested on stocks, crypto, and more.
- Make sure that this indicator and your plotted chart are on the same scale, otherwise will look like floating, will move and would seem like it does not matches the chart.

Important Note
- The alerts and shapes only trigger after the "End Date" of the slope, not before or between them
