关于币安限价订单价格与数量取整的正确性验证问询

在币安创建限价订单时，尤其是设置止盈/止损比例或计算下单数量的环节，必须依据交易所信息API返回的过滤器规则对价格和数量进行取整处理，否则订单创建请求会直接失败。

我发现Binance.Net库中的ClampPrice方法仅实现了基础的最小-最大值限制逻辑，这并不完全符合币安的过滤规则。因此我自己编写了一个扩展方法，针对价格按BinanceSymbolPriceFilter.TickSize取整，针对数量按BinanceSymbolLotSizeFilter.StepSize取整，代码如下：

public static class BinanceHelpers
{
    public static decimal RoundStepSize(decimal priceOrQuantity, decimal stepSize) => priceOrQuantity - priceOrQuantity % stepSize;
}

我需要从币安官方API文档这类可信来源，确认这个方法的正确性和完整性。

以下是交易所信息端点返回的BTC/USDT过滤器信息：
