PriceChannel:

A price channel based on a bar of user-defined duration (timeframe).

Author: fxsaber

 
If you want the lower bound to be calculated by bid
#define  PRICECHANNEL_LOW_PRICE bid  // bid/ask/last for Low bar
#include <fxsaber\PriceChannel\PriceChannel.mqh>
  
// Example of PriceChannel library operation on 10-second bars: TF = S10.
 
input int inPeriod = 23; // Channel period
input int NumBar = 12;   // Number of the bar whose data we will output

#include <fxsaber\PriceChannel\PriceChannel.mqh> // https://www.mql5.com/en/code/23418

PRICECHANNEL PriceChannel(inPeriod); // Created PriceChannel, the bar duration coincides with the chart bar.

void OnInit()
{
  PriceChannel.SetBarInterval(10); // Count 10-second bars: TF = S10.
  
  OnTick();  
}

#define  TOSTRING(A) #A + " = " = (string)(A) + "\n"

void OnTick()
{
  static const datetime StartTime = TimeCurrent();
  
  PriceChannel.NewTick(); // Threw a tick into the channel
  
  const MqlTick Tick = PriceChannel[NumBar]; // Get the High and Low of the corresponding S10 bar

  const string Str = "Duration = " + TimeToString(TimeCurrent() - StartTime, TIME_SECONDS) + "\n\n" +
  
                     "Length of the timeframe = " + (string)PriceChannel.GetBarInterval() + " seconds\n" +
                     "PriceChannel's period = " + (string)PriceChannel.GetPeriod() + " bars\n\n" +

                     "Highest[" + (string)PriceChannel.GetPeriod() + "] = " + DoubleToString(PriceChannel.GetHigh(), _Digits) + "\n" +
                     "Lowest[" + (string)PriceChannel.GetPeriod() + "] = " + DoubleToString(PriceChannel.GetLow(), _Digits) + "\n\n" +
                     
                     // It is possible to count the channel even if the period is not specified
                     "Highest[" + (string)inPeriod + "] = " + DoubleToString(PriceChannel.GetHigh(inPeriod), _Digits) + "\n" +
                     "Lowest[" + (string)inPeriod + "] = " + DoubleToString(PriceChannel.GetHigh(inPeriod), _Digits) + "\n\n" +

                     // Corresponding S10 bar values
                     "High[" + (string)NumBar + "] = " + DoubleToString(Tick.bid, _Digits) + "\n" +
                     "Low[" + (string)NumBar + "] = " + DoubleToString(Tick.ask, _Digits);
                     
  PriceChannel.SetPeriod((PriceChannel.GetPeriod() + 1) % 100); // You can change the channel period

Tested under MT4 on an Expert Advisor with adaptive periods PriceChannels.


Time of a single run without the library

755160 tick events (17243 bars, 756161 bar states) processed in 0:00:04.868 (total time 0:00:05.008)


With library

755160 tick events (17243 bars, 756161 bar states) processed in 0:00:02.293 (total time 0:00:02.434)


Otherwise everything is identical.


I.e. even in MT4 Optimisation can be twice as fast. The acceleration is a bonus, it was not done for this purpose.

 
No plans to add bar plotting by number of ticks and by traded volume?

There are no plans for this library.
