TASK：
新增查询用户可用杠杆倍数和切换杠杆倍数的接口。

Shecdule:
2020-10-20 到 2020-10-21

单元测试：
查询用户可用杠杆倍数（/linear-swap-api/v1/swap_available_level_rate ） 通过
切换杠杆（/linear-swap-api/v1/swap_switch_lever_rate ） 通过

集成测试：
通过

I use huobiCrossAPIService.swapCrossOrderRequest to place the order. It produces the Request:

Request{
  method=POST, 
  url=https://api.hbdm.com/linear-swap-api/v1/swap_cross_order?
    volume=1&
    lever_rate=10&
    SignatureVersion=2&
    offset=open&
    contract_code=BTC-USDT&
    AccessKeyId=h6n2***&
    Signature=yHZS***&
    SignatureMethod=HmacSHA256&
    order_price_type=opponent&
    Timestamp=2021-10-18T11%3A38%3A06&
    direction=buy, 
  tag=null}

in response I get:

SwapCrossOrderResponse(status=ok, data=SwapCrossOrderResponse.DataBean(orderId=89***76, orderIdStr=89***76, clientOrderId=null), ts=1634557188608)

Then I need to place TPSL order. I naively tried to fill request parameters as follows:

val request = SwapTpslOrderRequest.builder()
  .contractCode(contractCode) // BTC-USDT
  .volume(volume.bigDecimal) // 1
 .slTriggerPrice(sellPrice) // currentPrice - 5.0
  .direction(DirectionEnum.SELL.getValue)
 .build()

which produces the Request:

Request{
  method=POST, 
  url=https://api.hbdm.com/linear-swap-api/v1/swap_cross_tpsl_order?
    volume=1&
    SignatureVersion=2&
    contract_code=BTC-USDT&
    AccessKeyId=h6n2***&
    sl_trigger_price=61251.2&
    Signature=rd7f***&
    SignatureMethod=HmacSHA256&
    Timestamp=2021-10-18T11%3A44%3A00&
    direction=sell, 
  tag=null}

and get the response:

{"status":"error","err_code":1069,"err_msg":"The price is not reasonable.","ts":1634557478538}

I use ceiling to tenths:

val sellPrice = (currentPrice - 5).setScale(1, RoundingMode.CEILING).bigDecimal
// currentPrice is the price of the contract from /linear-swap-notification

which fits the price_tick of BTC_USDT. I don't know the reason of “price is not reasonable”.

Please, explain how to connect TPSL order with an existing opened long position?

测试类是com.huobi.linear.swap.api.TradeAPITest类的swapOrderRequest()方法
//填写申请的API-KEY 和 SECRET
HuobiAPIServiceImpl huobiAPIService = new HuobiAPIServiceImpl("API-KEY", "SECRET");
@test
public void swapOrderRequest() {
SwapOrderRequest request = SwapOrderRequest.builder()
.contractCode("BTC-USDT")
.volume(100l)
.price(BigDecimal.valueOf(10121))
.direction(DirectionEnum.SELL)
.offset(OffsetEnum.OPEN)
.leverRate(5)
.orderPriceType("opponent")
.build();
SwapOrderResponse response =
huobiAPIService.swapOrderRequest(request);
logger.debug("1合约下单：{}", JSON.toJSONString(response));
}

用这个方法 提示 {"status":"error","err_code":1047,"err_msg":"Insufficient margin available.","ts":1622033531177}
