TradingView Script for Stock Price Alerts

I need a TradingView script that will notify me in real time when specific price levels are hit for certain stocks. The price levels to monitor are:
- Today’s Premarket high
- Today’s Premarket low
- Yesterday’s High of the day
- Yesterday’s Low of the day

The stocks that need to be monitored by this script are:
- SPY
- QQQ
- TSLA
- NVDA
- AAPL
- AMD
- GOOGL
- AMZN
- META

In addition to the alerts, I would like visual markers on the chart for the specified price levels. The alerts should be sent as TradingView notifications.

Ideal Skills:
- Experience with TradingView scripting
- Knowledge of stock trading and price levels
- Ability to create visual markers on TradingView charts

Please note that I need the alerts to be in real-time.
