· The Idea ·

Most people are afraid to try crypto trading because one wrong move costs real money. FunTrade removes that fear — connect to live market data, trade with virtual capital, and learn through real mechanics: Long/Short positions, Stop-Loss, Take-Profit, PnL tracking. When you're bored of the charts, spin the slot machine.

Open app  →  Watch live prices  →  Open trade  →  Track PnL  →  Close & repeat

Layered architecture — service calls flow up, state flows down, UI just watches.

· Trading Logic ·

How a trade lives and dies:

1. OPEN
   User taps Buy/Sell
   └─ PortfolioProvider.openTrade(asset, direction, size)
      └─ entryPrice recorded
         └─ size deducted from virtual balance
            └─ StorageService.save()

2. LIVE
   MarketProvider ticks every 5s
   └─ PortfolioProvider.onPriceUpdate(newPrice)
      └─ PnL = (currentPrice − entryPrice) × size
         └─ Check Stop-Loss / Take-Profit
            └─ Auto-close if threshold crossed → go to step 3

3. CLOSE
   User taps Close (or SL/TP triggers)
   └─ PortfolioProvider.closeTrade(position)
      └─ Final PnL added to balance
         └─ TradeHistory entry created
            └─ StorageService.save()
