Need Help to develop a tick indicator for MAG7 stocks

[BETrader]

Dear Thinkscript community,

I have developped this script for ticks (based on same indicator developped by simpler trading):


I would like to modify this code to have the same thing with the MAG7 stocks: AAPL, AMZN, GOOGL, META, MSFT, NVDA, TSLA. Could you please help me ? I am a newbie with Thinkscript !
Many thanks in advance for your help
