How can we help?
Everything you need to know about HC.exchange and HealthCoin Rewards (HCR).
HC.exchange currently supports the following trading pairs: HCR-USD, MHC-USD, DMC-USD, and FTC-USD, with HCR-HCC launching as the primary HCC-denominated pair. HCR-USD offers the deepest current liquidity. Community chain pairs (MHC, DMC, FTC) are available as pilot listings. BTC and ETH are accepted as deposit currencies to fund your account — they are not trading pairs. Additional pairs are added as community chains are approved.
A market order executes immediately at the best available price in the order book. You are guaranteed execution but not a specific price — especially relevant in lower-liquidity pairs. A limit order lets you specify the exact price at which you want to buy or sell. Your order is placed in the order book and only fills when the market reaches your target price. Limit orders are the recommended method for trading HCR to minimize slippage.
Paper Trading mode is a simulated trading environment that uses real-time market data but executes trades with virtual funds. It is designed for new users who want to practice trading strategies without financial risk, and for developers testing integrations against the HC.exchange API. Paper Trading balances are completely separate from live balances and cannot be withdrawn. You can toggle Paper Trading mode in your Account Settings.
The order book is a real-time ledger of all open buy (bid) and sell (ask) limit orders for a given trading pair. Bids are sorted from highest to lowest price; asks are sorted from lowest to highest. When a new order is placed, the matching engine checks whether it can be filled against existing orders. If a buy price meets or exceeds the lowest ask, the trade executes. The price displayed on the exchange reflects the last matched trade.
Yes. The minimum trade size on HC.exchange is 0.01 HCR across all trading pairs. This minimum applies to both market and limit orders. There is no maximum trade size, though very large orders may be subject to additional compliance review depending on your KYC tier.
Market orders are typically filled within milliseconds under normal market conditions. Limit orders remain open in the order book until the market price reaches your specified level, which may be seconds, hours, or never — depending on where you set your price relative to the market. You can view all open and historical orders in the Orders section of your account dashboard.
