VAR order: Torder;
Order.symbol: = ‘BTC/USDT’;
Order.Side: = Order.buy;
Order.quaantity: = 1;
Order.marketprice: = Float64 (1000.00);
Order.Pricingfee: = floting64 (10.00); // assume a 10%fee
Order.Sellingfee: = floating64 (20.00); // assume a 20%fee
// triying to make an order

problem
In this example, we will try to take place the boarder purchase (buy) Bitcoin/USDT with the Binance application interface. We define from application subscription information and receive the current account balance. There is desired features.
Finally, we try to place an order use Api.order ('boarder', 'buy', order).
Solution
To solve that problem you need to:
– Binance’s API users a specal signature system for boarders.
- Check your account balance : Make of your yourscunt has a loss ing to your order.
- Use the rights of control features
: Check the double control ubject properties, that you will ‘api.order ()
. In particular, make of the "MarketPrice" field correspons to the price you want.

// Set the Binance API operating data (API key, secret key)
arm
Mirikey: string;
Apisecret: sliding;
// platform Binance API object
API: = tbinancei.create;
API.Setapikey (Mirikey);
API.Setapisecret (Apisecret);
// Get youurent account balance
Var balance: integer;
If API.GetBalance (‘ETH’, ‘USDT’, Balance, zero, zero)
Writeln (‘account balance is valid.’);
other
Writeln (‘Getting an error account balance:’, api.getbalanceerror);
end;
// Create a new order
VAR order: Torder;
If order.SYMBOL = ‘BTC/USDT’
Order.Side: = Order.buy;
Order.quaantity: = 1;
Order.marketprice: = Float64 (1000.00); // assume that way price is $10,000
Order.Pricingfee: = floting64 (10.00); // assume a 10%fee
Order.Sellingfee: = floating64 (20.00); // assume a 20%fee
// triying to make an order
If Api.order (‘Border’, ‘Buy’, Order)
Writeln (‘order placed succexfully!’);
