`

Private Api Example

Please refer to private api

`typescript
let apexClient = new ApexClient.omni(OMNI);
const apiKeyCredentials: ApiKeyCredentials = {
key: 'api key',
passphrase: ' passphrase ',
secret: ' secret',
};
const seed: string = "your omnikey";
await apexClient.init(apiKeyCredentials, seed);

// 'GET Trade History'
const { orders } = await apexClient.privateApi.tradeHistory(BTC-USDT, 'OPEN');

//'GET Open Position '
const account = await apexClient.privateApi.getAccount(apexClient.clientConfig?.accountId, apexClient.user?.ethereumAddress);
const positions = account?.positions


`

Please refer to create_order demo

`typescript
let apexClient = new ApexClient.omni(OMNI);
const apiKeyCredentials: ApiKeyCredentials = {
key: 'api key',
passphrase: ' passphrase ',
secret: ' secret',
};
const seed: string = "your omnikey";
await apexClient.init(apiKeyCredentials, seed);

// 'POST Create Limit Orders'
const symbol = BTC-USDT;
const price = '100000';
const size = '0.01';
const baseCoinRealPrecision = apexClient?.symbols?.[symbol]?.baseCoinRealPrecision;
const takerFeeRate = apexClient.account.contractAccount.takerFeeRate;
const makerFeeRate = apexClient.account.contractAccount.makerFeeRate;

const limitFee = new BigNumber(price)
.multipliedBy(takerFeeRate || '0')
.multipliedBy(size)
.toFixed(6, BigNumber.ROUND_UP);

const apiOrder = {
pairId: apexClient.symbols[symbol]?.l2PairId,
makerFeeRate,
takerFeeRate,
symbol,
side: OrderSide.BUY,
type: 'LIMIT',
size,
price,
limitFee,
timeInForce: 'GOOD_TIL_CANCEL',
} as CreateOrderOptions;

const result = await apexClient.privateApi.createOrder(apiOrder);
