How to create fully customisable alerts in pinescript

//@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")
