This is my first script, completely made from scratch. Bear with me.
Script that allows one to set an alert for Multiple Price Levels, on Multiple Tickers, complete with Dynamic Messages showing you which ticker, at which price, at which alert (Stop loss, Target 1 etc.), set to Once Per Bar.
Select Ticker, type in price levels that you have for targets & stop loss, move on to the next, or don't and leave 0 and blank.
Disable the targets you do not need in STYLE tab to disable plotting & scaling, leave unused tickers & targets blank & 0.
Create Alert, select this indicator, anyfunction() alert.
MAKE SURE to remake the alert every time you change something, they are not smart enough to change as you change things. Can Confirm by using the numbers in the alert name. You will also have to set the profit level or stop loss to zero every time it triggers to avoid triggered again.
In fact, you do not need the indicator active at all. Add it to a chart and hide it by clicking on the little eyeball icon, to make an alert open the settings for the indicator and type in your targets like normal. Indicator will remain invisable.
I have not found a way to dynamic message the alert name, or else I would.
DISCLAIMER: NONE OF THIS IS FINANCIAL ADVICE. You are completely responsible for whatever happens to you. Do not use the targets in this chart. Do your own research before trading.
