Instant trading instrument

[Sapphire]

Hi all!

I'm developing a useful service for traders. So far it is an interface for BTC-e API. Features:

• you buy/sell instantly, without typing prices and amounts
• the trade is done at the current best market price
• you trade with the whole available balance
• you are sure the trade will be done right away, without any orders left in the orderbook
• you see estimated effective price of your trade before you do it; it analyses the market depth, your balance and fee
• all BTC-e pairs are available for trading

Check it out: http://instanttrader.org
There's a demo account to see what it is. You can register your own and use your API key. It has no access to withdrawing your money, API only allows trading.

Coming shortly:

• market history and market depth
• nice charts
• more exchanges

I want to know your opinion on this. Can it be useful for you? What features would you like to see there? Which ones are the most important ones to implement?

Hi! Here's an update.

Now Instant Trader has market history and order book displayed.
I decided to switch from depth to just order book. Please, let me know, what's more necessary for you? Do you need order book or depth more? Or maybe it's worth dedicating some screen space to both?

Right now Instant Trader refreshes market info every 10 seconds. I will speed it up as soon as people start needing it.

Now I'm working on charts.

Other things to implement shortly:

• other types of buy/sell buttons as alternatives (with price typing, with some nice features)
• enable you to control your market orders
• add more exchanges (probably Cryptsy, Bter, Vircurex, make your suggestions)

Please let me know what features you need the most, I'll implement them in the first place to make the instrument as good as it can be.

Can you integrate with a spreadsheet?

Can you integrate with a spreadsheet?

Yes, but what kind of integration do you need exactly? You want some extra calculations done or just log your trading or just export something into a spreadsheet file? Or something else?

Trading the whole available balance sounds incredibly scary. Allow people to set limits.
