  1. so what is the problem? you can have a two-dimensional array, second dimension must be fixed, first can be dynamic and change. e.g. int array[][3]; then add more elements by using ArrayResize function - it is well documented so please show what you did and why it does not work so that we will try to help you wiht your code
  2. What's new in MQL5 Added functions for quick insertion, deletion, copying and expanding array elements. The new ArraySwap() function swaps the contents of two dynamic arrays of the same type, while the ArrayPrint() function allows you to easily print an array of a simple type or a simple structure in the journal
  3. The ArrayResize() function allows to set size of an array with a reserve for further expansion without the physical relocation of memory. It is implemented for the better performance, because the operations of memory relocation are reasonably slow

Function. Action. MathAbs. Returns absolute value (modulus) of the specified numeric value. MathArccos. Returns the arc cosine of x in radians. MathArcsi Object Functions. This is the group of functions intended for working with graphic objects relating to any specified chart. The functions defining the properties of graphical objects, as well as ObjectCreate() and ObjectMove() operations for creating and moving objects along the chart are actually used for sending commands to the chart

If the element with the specified value ia absent then the function will return the index of the nearest (by value) element. ArrayCopy : It copies one array to another. The arrays must have the same type. The arrays of the double[], int.
  2. Function. Action. SetIndexBuffer. Binds the specified indicator buffer with one-dimensional dynamic array of the double type. IndicatorSetDouble. Sets the value of an indicator property of the double type. IndicatorSetInteger. Sets the value of an indicator property of the int type. IndicatorSetString. Sets the value of an indicator property of.
  3. I'm trying to create an Array in MQL4, and on every tick I want to add a new value to array[0] and push the rest of the items back, so the old array[0] becomes array[1] and array[1] becomes array[2] and so on. I want to be able to do this an unlimited number of times, once per tick. Then I can access the value from the previous tick using array[1], but I can also access its current value array.

  5. Economic calendar functions. This section describes the functions for working with the economic calendar available directly in the MetaTrader platform. The economic calendar is a ready-made encyclopedia featuring descriptions of macroeconomic indicators, their release dates and degrees of importance
  6. Okay, first we need to create an array for the price data, this one will be called: TenkansenArray because the red line you see here is the Tenkan-sen line and we use the function: iIchimoku that comes with MQL5 for the current symbol on the chart and the currently selected period. These 3 values here can also be found when you click on: Insert/ Indicators/ Trend/ Ichimoku Kinko.
  7. ArraySetAsSeries() function makes sure that the array is indexed as a time series. 0 in the CopyRates() function means that the time series most recent value will be indexed as 0 and the value before that will be indexed as 1 and so on. So we are moving backward when we deal with time series in MQL5. 3 in CopyRates() function means we only save the last three bars. Below is the predefined.
