Simfolio

Start with a cash balance and build a portfolio from scratch. Search across 30,500 US-listed stocks and ETFs, place buy and sell orders at live market prices, and see exactly what an order will cost, and what your cash and share count will look like afterwards, before you confirm it.

Your portfolio is valued continuously against live prices rather than frozen at page load. Total value, buying power, how much of your cash is deployed, and unrealized profit and loss all move as the market does. Average cost blends when you buy more, and selling part of a position realizes only that share of the gain.

Every symbol has its own page: a price chart across six time ranges, company fundamentals like market cap, P/E and dividend yield, and a trade panel that never leaves the screen. Add anything to a watchlist with one tap. It updates instantly and quietly syncs in the background.

Top up your practice cash whenever you want, and review every buy, sell, and deposit in a running activity feed with the exact price and timestamp each order filled at.
