I'm definitely no pro, just a homebody retail coder. I don't code for anybody but myself.Google sheets is the wrong tool for the job. IMO
You are way better using any server side programming language and then, if you need a UI use Socket.IO to display any data on a local website.
Would you care to describe in bullet points what would be the content of your course and why did you choose Google Sheets over any other platform?
A developer wouldn't use Google Sheets for trading, is it fair to say that you are not a developer?
Neither am I on social media other than ET, neither do I publish content other than privately to a couple of friends, although that now discontinued as it had got to the stage they now need stand on their own two feet.
Google sheets suits me as it is free, updates automatically and the 'excel' language/formulas I love working with, it's easy.
If you subscribe to a charting package for ASX, you'll maybe only get OHLCV, delayed usually EOD and pay a hefty price and then only ASX.
Sheets offer streaming data day and night for several exchanges:
“price” Stock price. In real-time but with a delay of up to 20 minutes.
“priceopen” Opening price (price at market open).
“high” High price of the current day.
“low” Low price of the current day.
“volume” The trading volume of the current day.
“marketcap” The market capitalization of the stock.
“tradetime” The time of the last trade of the stock.
“datadelay” The delay time for the real-time data.
“volumeavg” The average daily trading volume.
“pe” Price-to-earnings ratio
“eps” Earnings per share
“high52” The highest price in the last 52 weeks.
“low52” The lowest price in the last 52 weeks.
“change” The stock price change since the end of yesterday’s trading.
“beta” The beta value
“changepct” The percentage change in price since the end of yesterday’s trading.
“closeyest” Yesterday’s closing price.
“shares” The number of shares outstanding.
“currency” The currency that the stock is priced in.
So there's quite a bit of data here on offer you can crunch a thousand different ways.
