数据用途

* 监控仓位数量(size)。当 size 从有变为 0 时,表示该方向被止盈条件单平仓, * 触发补仓(reopenLongPosition / reopenShortPosition)。 * *

推送字段

注意

* 双向持仓模式下空头 size 为负数,使用 {@code size.abs()} 判断是否有仓位。 * 累计盈亏不由本频道计算,而是由 {@link PositionClosesChannelHandler} 独立处理。 * * @author Administrator */ @Slf4j public class PositionsChannelHandler extends AbstractPrivateChannelHandler { private static final String CHANNEL_NAME = "futures.positions"; public PositionsChannelHandler(String apiKey, String apiSecret, String contract, GateGridTradeService gridTradeService) { super(CHANNEL_NAME, apiKey, apiSecret, contract, gridTradeService); } @Override public boolean handleMessage(JSONObject response) { if (!CHANNEL_NAME.equals(response.getString("channel"))) return false; try { JSONArray resultArray = response.getJSONArray("result"); if (resultArray == null || resultArray.isEmpty()) return true; for (int i = 0; i < resultArray.size(); i++) { JSONObject pos = resultArray.getJSONObject(i); if (!getContract().equals(pos.getString("contract"))) continue; String mode = pos.getString("mode"); BigDecimal size = new BigDecimal(pos.getString("size")); BigDecimal entryPrice = new BigDecimal(pos.getString("entry_price")); log.info("[{}] 持仓更新, 模式:{}, 数量:{}, 入场价:{}", CHANNEL_NAME, mode, size, entryPrice); if (getGridTradeService() != null) { getGridTradeService().onPositionUpdate(getContract(), mode, size, entryPrice); } } } catch (Exception e) { log.error("[{}] 处理数据失败", CHANNEL_NAME, e); } return true; } }
