1. How to open a position at the opening price

• Contract address: 0x1b6f2d3844c6ae7d56ceb3c3643b9060ba28feb0

• Method: openMarketTrade

• Parameters: data (tuple) Tuple: A tuple is an array of values e.g. [ "0x4sd…","100","100"..]. It can contain strings, integers, and boolean values. The structure for this tuple is:

struct OpenDataInput {
        // Pair.base
        address pairBase;
        bool isLong;
        // BUSD/USDT address
        address tokenIn;
        uint256 amountIn;   // tokenIn decimals
        uint256 qty;        // 1e10
        // Limit Order: limit price
        // Market Trade: worst price acceptable
        uint256 price;      // 1e8
        uint256 stopLoss;   // 1e8
        uint256 takeProfit; // 1e8
        uint256 broker;
    }

Example: If the user wants to use 100 USDT to place a pending order for a BTC Long position with Price 20000, Quantity 0.001, Take Profit Price 25000, and Stop Poss price 19000, the inPutData should be:["0x7130d2a12b9bcbfae4f2634d864a1ee1ce3ead9c","True","0x55d398326f99059fF775485246999027B3197955","100000000000000000000","10000000",,"2000000000000"2500000000000","1900000000000",1]

2. How to place a limit order

• Contract address: 0x1b6f2d3844c6ae7d56ceb3c3643b9060ba28feb0

• Method: createLimitOrder(

• Parameters: data (tuple)

struct OpenDataInput {
        // Pair.base
        address pairBase;
        bool isLong;
        // BUSD/USDT address
        address tokenIn;
        uint256 amountIn;   // tokenIn decimals
        uint256 qty;        // 1e10
        // Limit Order: limit price
        // Market Trade: worst price acceptable (acceptable price=index Price*(1+/- spread)
        uint256 price;      // 1e8
        uint256 stopLoss;   // 1e8
        uint256 takeProfit; // 1e8
        uint256 broker;
    }
