double iMACD (
string symbol , // symbol
int timeframe , // timeframe
int fast_ema_period , 技术指标 // Fast EMA period
int slow_ema_period , // Slow 技术指标 EMA period
int signal_period , // Signal line period
int 技术指标 applied_price , // applied price
int mode , // line index
int shift // shift
);

[in] Symbol name on the data of which the indicator will be calculated. NULL means the current symbol.

[in] 技术指标 技术指标 Timeframe. It can be any of ENUM_TIMEFRAMES enumeration values. 0 means the current chart timeframe.

QoS的重要性

QoS的度量指标

QoS的应用场景

网络协议和管理协议(如OSPF、Telnet)

实时业务(如视频会议、VoIP)

QoS的服务模型

Best-Effort服务模型:尽力而为

IntServ服务模型:预留资源

IntServ模型使用了RSVP(Resource Reservation Protocol)协议作为信令,在一条已知路径的网络拓扑上预留带宽、优先级等资源,路径沿途的各网元必须为每个要求服务质量保证的数据流预留想要的资源,通过RSVP信息的预留,各网元可以判断是否有足够的资源可以使用。只有所有的网元都给RSVP提供了足够的资源,“路径”技术指标 方可建立。

对比QoS和HQoS

  • 传统QoS是基于端口带宽进行调度的,因此流量管理可以基于服务等级进行业务区分,却很难基于用户进行区分,因此比较适合部署在网络核心侧,但不适合部署在业务接入侧。
  • 传统QoS无法做到同时对多个用户的多个业务进行流量管理和调度。

为了解决上述问题,人们需要一种既能区分用户流量又能根据用户业务的优先级进行调度的技术,HQoS(Hierarchical Quality of Service,层次化QoS)应运而生。HQoS通过多级队列进一步细化区分业务流量,对多个用户、多种业务等传输对象进行统一管理和分层调度,在现有的硬件环境下使设备具备内部资源的控制策略,既能够为高级用户提供质量保证,又能够从整体上节约网络建设成本。

Calculates the Relative Strength Index indicator and returns its value.

double iRSI (
string symbol , // symbol

int applied_price , // applied price
int shift // shift
);

[in] Index of the value taken from the indicator buffer (shift relative to the current bar the given amount of periods ago).

Numerical value of the 技术指标 Relative Strength Index indicator.

if ( iRSI ( NULL ,0,14, PRICE_CLOSE ,0)> iRSI ( NULL ,0,14, PRICE_CLOSE ,1)) return (0);

BTCUSDT: Faust

Faust is a composite 技术指标 indicator that combines 3 volume indicators: TSV, OBV, and PVT. TSV moving average is plotted as an oscillator. OBV and PVT are calculated internally.
