Hey Product Hunt 👋 I'm Vishal, and I built Papertrade.
I wanted one place to practise day trading in any market, and to test something new: AI agents that trade. More people are letting Claude or ChatGPT read the market and place orders, but there was nowhere safe to check whether those decisions are any good. So I built a simulator that both people and AI agents can use.
What you can do
Trade 45 stock markets with virtual money, on each exchange's own hours, holidays and currency
Day-trade live prices, or replay any recent day minute by minute at up to 120× speed
Pick your real broker (Zerodha, Robinhood, Trading 212, CommSec and 170 more) so every fill pays its actual fees and local taxes
Use market, limit and stop orders with stop loss, target and trailing stops, then read a results report with win rate and costs
Connect Claude, ChatGPT, Cursor or any MCP client, let it trade, and watch every call it makes
It's free with no credit card. I'd love your feedback, especially on which markets, brokers or AI workflows you want next.
