How do ETFs tracking another country's markets work? (trading, Vanguard, stock)

[arctic_gardener]

I purchased $5000 of an ETF tracking India's Nifty index two weeks ago (it has gained 7% since then ). Since the ETF is listed on the Toronto Stock Exchange, how exactly does it track the markets of a country where the trading session is over for the day?

Which brings me to my next question (bear with me that I'm new to investing): can leveraging 2x or 3x be more likely to succeed for an ETF that is tracking a market several time zones ahead?

they use what is called fair value pricing. the pricing is based on estimates of what is anticipated and not what actually happens.
