Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. Does somebody know how to avoid the error array out of range when trying to display long number of bars lets say in an indicator buffer?

As of a "New"-MQL4. I had a similar issue, that I always got " Array out of range " errors for one of my buffers. I checked with ArraySizewhich returned 0. In the end I just forgot to call SetIndexBuffer Since I was using an internal buffer without drawing lines, I used the IndicatorBuffers function to increase the amount of buffers first and then registered my additonal buffer using SetIndexBuffer Learn more. How to avoid array out of range Ask Question.

While the arrays problem look similar, there is a major difference MQL4 Indicators use "other" mechanics for handling arrays than "ordinary" arrays have. Testing pass stopped due to a critical error in the EA And one ought to review on each New-MQL4. Indicators use array indirectly, via an automated Buffer-handler In this sense, your code need not care about these issues.

Feedback on Q2 Community Roadmap.Hello guys, im getting the following error: " array out of range in 'IndicadorV1. I've try changing the ArrayResize and getting it before the med[i], and it works, but it doesnt do anything. But if i try to change the "" for the "i" parameter, then it gives the array out of range error I have tried to do a not dynamic array, and it doesnt gives the error, but it doesnt do aynthing at all either There's any way i could see how the array if getting filled??

Yes, i know. Maxmix value becomes True in some point of the code. But, the most important thing so i can try to fix it myself, i want to know how the array is getting filled? And one last question The first " i" in yellow changes, because it prints the med[1],med[2], Array out of range.

To add comments, please log in or register. Alvaro Thanks guys. How you store the iMA values of 0,1,2 current, prev1bar, prev2bar?

Keith Watford GumRai : If you resize an array to i the array contains med[0] to med[i-1] med[i] does not exist and so you will get the array out of range error. GumRai : That will print them to the expert log. Compi : Any idea why this could happend??? WHRoeder : Compi : Any idea why this could happend???

Thanks guys! Trailing stop in my Trailing Stop. I have absolutely no idea what you are trying to achieve with your code. I find it impossible to follow the logic. Well, I may be able to given time. But I am not going to spoend 2 or 3 hours trying to unscramble your code. Should the condition never occur, you will be putting zeros in the array. If you used property strict you would have errored instead. Play video.

Please edit your post. We have no idea if i is changing. There are no mind readers here; you need to post the code.The functions of custom indicators allow you to adjust the necessary settings to make a convenient representation of an indicator.

Let's consider some of them see also Creation of Custom Indicators. The function joins an array-variable that was declared on the global level with a predestined custom indicator buffer. The amount of buffers that are necessary for indicator computation is set using the IndicatorBuffers function and cannot exceed 8. In order to get the detailed information about an error you should call the GetLastError function.

Can be one of the listed types of indicator lines see Styles of Indicator Lines Displaying. Used for the lines of 1 pixel width. Can be one of the line styles specified in the Styles of Indicator Lines Displaying appendix.

The function allows to set an indicator line name to be displayed in DataWindow and in the pop-up tip. The example of the simple indicator showing High line indicatorstyle. Block contains general settings of an indicator. It is specified with the property command that the indicator must be drawn in the main window, the indicator uses one buffer, the color of the indicator line is blue. One buffer array is opened in blockas well.

The entry:.

How to find largest and smallest values in an array in java?

The specified name can be seen in the DataWindow and in the balloon tip in the window of financial instrument fig. The naming of the lines is convenient, if the window contains a number of indicator lines; sometimes it is the only way to distinguish one line from another. Block performs the calculation of the values of indicator array elements for the line that is used to display the maximum values of bars the sequence of indicator arrays calculation is described in the Creation of Custom Indicators section in detail.

If the indicator is displayed in a separate window, then the horizontal levels can be displayed in this window too. Sets the value for the specified horizontal level of the indicator that is displayed in a separate window.

The use of horizontal levels can be very convenient, if you need to detect visually whether the indicator line is above or below the specified values. The simple indicator that calculates the difference between the maximum and the minimum price of the bar is shown below. The market events are interesting for the user tentatively in this example if the indicator line is above the bar by 0. The example of the indicator that displays the difference between High and Low linelevel.

The considered function is used in block in the indicator. In this case, two horizontal levels are specified. The first value in the list of parameters is the number of the horizontal level, the second one is the specified value of the level:. The parameters of indicatorstyle. Displaying indicators settings in different windows of the client terminal. Two windows - the DataWindow and the financial instrument window are shown in the fig.

You can see the entry containing "High Line" text and the 1. The same inscriptions are shown in the lower entry of the pop-up tip. The said entry is displayed in the DataWindow the whole time the indicator runs, the name of the line is not changed at that, but the value in the right part of the entry depends on the cursor position in the financial instrument window.

The name of the line that is shown in the pop-up tip corresponds to the indicator line the cursor is pointed at. The subwindow of the linelevel. If you move the cursor over the red indicator line then the name of this line, in this case the "Difference between High and Low", can be seen in the pop-up tip, the value at the cursor point can be seen to the right of the name.The function sets a new size for the first dimension. Distributed size to get reserve.

If executed successfully, it returns count of all elements contained in the array after resizing, otherwise, returns -1, and array is not resized. The function can be applied only to dynamic arrays. It should be noted that you cannot change the size of dynamic arrays assigned as indicator buffers by the SetIndexBuffer function.

For indicator buffers, all operations of resizing are performed by the runtime subsystem of the terminal. Total amount of elements in the array cannot exceed With the frequent memory allocation, it is recommended to use a third parameter that sets a reserve to reduce the number of physical memory allocations. All the subsequent calls of ArrayResize do not lead to physical reallocation of memory, but only change the size of the first array dimension within the reserved memory.

It should be remembered that the third parameter will be used only during physical memory allocation. For example:. In this case the memory will be reallocated twice, first before entering the element loop the array size will be set toand the second time with i equal to If we skip the third parameter, there will be physical reallocations of memory, which will slow down the program.Can anyone explain to me how I would set a custom indicator into a series array?

mql4 array max

I did read somewhere that explained I would need to place the indicator into a series array then do ArrayMaximum and ArrayMinimum to get the value for the highest and lowest values. But I have no idea how to do this? I understand why it would need to be done, as the values of the custom indicator would need to be stored and sorted probably so that the function arraymaximum can find the value wheres it would not be able to do so if it wasnt a series array.

But I am not sure how the index is determined when there are multiple highs or lows. To give an example, I am producing the code from the help:. Why not index 9 or 15? The question is "what is the highest value". The answer is 9, which can be found in index 4. Highest and lowest value of indicator. To add comments, please log in or register.

There are no difficulties in using most of them. For example, the MathMax function returns the maximum value of two values specified in the list of parameters of the function. The usage of other functions claims certain attention and thoughtfulness.

Let's examine one of the functions of this kind. The function returns a numeric value that corresponds the greatest integer that is less or equal to x. Note that a value returned by the function is the real number double typeat the same time, it is written that the function returns an integer.

It should be realized that the function returns a real number that has all the positions equal to zero after the decimal point. For example, the MathFloor function may return The description says also that the function returns the maximum of possible numbers that is less than a specified one.

For example, if the value of the given x parameter is Or if the In such a manner, modification of the sign of the passed to the function value leads to the different results, namely the received values are not equal to each other in absolute magnitude.

Usage of such functions is very convenient, in some cases. Let's examine the fragment of the lots amount calculation for new orders as an example:. The value of the Percent parameter is set by user. According to the rules that are specified by the dealing center, the correctly calculated amount of lots must be divisible by the minimum step of lots changing size Step.

Let's use the numeric values of the variables for better visualization. The In this case, the price of a new order may reach the Spending all these money you can open one new order that has the To calculate the desired amount of lots you should throw away all the "needless" digits in the decimal part and replace them with zeros.
