I am beginner in crypto-currencies, i just created my account in cryptsy and can make buy/sell orders but how do i accept orders from others(i.e open orders(all buy/sell orders)) i can view the list of all buy/sell orders but don't know how to accept those orders?

You cannot accept or reject an order. When you place a sell order (for clarity's sake assume 1 BTC for 100 dollar) and there is no-one with a buy order above $100/BTC you end up in the list of buy orders. When someone thinks "hmm, that is a nice price to pay for a bitcoin" he can create a buy order for 1 BTC (or less) for $100/BTC. Cryptsy looks then if there is a sell order for that price (or lower) and his order will be filled, and you get your money. So if you leave an order open while you go away, it can be filled without you noticing it.

If you want more clarity about the filling of orders, you can look at my answer here.

edit: so if you want to close the deal immediately, buy (or sell) at a rate that there is a seller who sells at that rate. Otherwise the market can go up, and your bid will be missed out.

  • Then all the orders are automated(match buy/sell) by cryptsy itself, Is there any opensource project available for trading? and i want to know what will happen at the back end – M.R May 02 '14 at 11:18
  • Yes, all orders are matched automatically by cryptsy. So don't worry when you want to buy something at $101.52351/BTC and no-one will like your not-round value. When you have the highest bid, your order will be matched automatically. For an opensource exchange I think it is best to refer you to Buttercoin but I have no clue if that suffices. If you meant something else, like a trading bot: pick your like. I tried to make them myself instead of copying it (much more to learn) – Mathias711 May 02 '14 at 11:22
  • And of course this applies for all exchanges out there, not just cryptsy. – Mathias711 May 02 '14 at 11:28
  • One more question, trading engine matches buy/sell orders, but how the amount got transferred to buyer/seller for e.g DOGE/BTC in different crypto-currency, Is it also done by trade engine? Buttercoin not at all work, anyother opensource trade engine in ruby? – M.R May 06 '14 at 05:41
  • The currency in the exchange is not really in wallets you can access. When you deposit 1 btc the site keeps track of that. When you trade 0.5 btc for 200 doge, the exchange knows you have 0.5 btc and 200 doge, but it's not in your wallet. When you withdrawal, it is transferred to your wallet of choice, and the exchange knows you have less btc/doge on the site. I don't know another open-source exchange, but it may be out there – Mathias711 May 06 '14 at 06:15
  • How the crypto-currency say DOGE coin is reduced in buyer and BTC increased in seller's balance? – M.R May 06 '14 at 06:25
  • I'm no expert in crypto exchanges, but there should be a large database with your balances. When you trade it is simply added or reduced from your previous amount – Mathias711 May 06 '14 at 06:27
  • Sure, no problem. Anything else, you ask :) – Mathias711 May 06 '14 at 06:30
