How to create fully customisable alerts in pinescript

9 227
Hi All,

As discussed in the video, below are the steps to define fully customisable alert templates and alerts in pine script. This is a generic idea which can be implemented for any script.

Step 1. What all parameters(keys) need to be sent in alerts.
Step 2. Create a default alert template
Step 3. Create a user input where users can alter the default alert template
Step 4. Define your alert condition.
Step 5. Calculate the values for all the keys
Step 6. In the template, replace all keys with values and send alert

Sample script developed during the video.

Pine Script®
//@version=5 indicator("Fully Customizable Alerts", overlay=true) import HeWhoMustNotBeNamed/RecursiveAlerts/2 as ra //Step 1. What all parameters(keys) need to be sent in alerts. keys = array.from("{entry}", "{stop}", "{target1}", "{target2}") //Step 2. Create a default alert template template = '{\n \t"entry" : {entry},\n \t"stop" : {stop},\n \t"target1" : {target1},\n \t"target2" : {target2}\n }' //Step 3. Create a user input where users can alter the default alert template inputTemplate = input.text_area(template, 'Alert Template') //Step 4. Define your alert condition. ma = ta.sma(close, 20) condition = ta.crossover(close, ma) atr = ta.atr(14) if(condition) //Step 5. Calculate the values for all the keys entry = high + atr stop = low - atr risk = entry - stop target1 = entry + risk target2 = entry + 2*risk //Step 6. In the template, replace all keys with values and send alert values = array.from(str .tostring(entry), str .tostring(stop), str .tostring(target1), str .tostring(target2)) alertMessage = ra.updateAlertTemplate(inputTemplate, keys, values) alert(alertMessage, alert.freq_once_per_bar) plot(ma, "Moving Average")
