Thank you in advance.

Can you make the following changes to the attached indicator.

1. Make the lines only go across part of the screen instead of the whole screen. See attached picture

2. Make it to where you can change line style. I want the line thickness as the smallest.


Could someone try to make the changes above in this indicator? It would be greatly appreciated.

{quote} Codix- I don't know your level of coding experience. Either you're way more experienced than I or you're fairly new to MQL. Either way its OK, all I'm saying is I've been at this for several years and have never had the need for such a function. I know coders who have but they way more advanced then I am. I have used the iCustom function in many EA's and indicators and have yet to use the OnTimer() function. It would have to be something very specific before I would consider using it.

Hello Cyber1,

I already told you. My indicator chokes mt4 when it is busy to run int start() for symbol A that started upon tick A and suddenly has to start int start() for symbol B because tick B has arrived.

I've added my scan indicator as a attachement and i've replaced OnTimer with int Start again. Also i've replaced all the custom indicators it scans with other indicators. You will need to install the mt4 terminal of FxPro http://www.fxpro.co.uk/trading/platforms/mt4/desktop in order to run this indicator properly (its called ScannerOnStart) because it is using the symbol names of FxPro (see the global string array declared above). I will give a short explanation of what this scanner indicator does.

1.It cycles to the next symbol out of Symbols[] on every new chart tick. When it gets to 216th symbol it resets back to 0.
2. Every symbol is analyzed with 22 indicators that return certain values that indicate either a buy signal or a sell signal.
3. It does this for 6 timeframes (15m,60m,4hr,1d,1w and 1mo) this is all enumerated and stored into the array TimeFrame[][].
4. When it is done scanning a symbol with the 22 indicators on all the different timeframes it constructs an alert message that
states for each time frame the total amount of indicators that either give a buying opportunity or a selling opportunity.

I have replaced the indicators with ADX,ADX1,ADX2,ADX3.......ADX21. Please put everything in the same map and run ScannerOnStart.
You will notice that the mt4 terminal chokes and freezes almost immediately. Could you please tell me why this is happening.

Kind regards and thanks in advance.

OnTimer is definitely the right place (IMHO) to run code accessing multi-timeframe, multi-symbol... but the amount of resources required for what you're describing is substantial to say the least.

Try dropping the max bars in chart settings right down. That's probably your only chance, coupled with regular terminal restarts.

why would i have to restart the terminal regularly? In the OnTimer function (which is set to 500ms) it processes one symbol at a every interval. It works fine when i only let it process EURUSD. Goes through the 6 timeframes smoothly and analyzes smoothly with the 22 indicators. On the second 500 ms interval it switches to the next symbol and then things go bad. I really need to know why... Are the 22 called indicators still configured for EURUSD on the second run? Should they somehow be purged out of memory first and then reinitialized for the second symbol????

Because max bars in chart only applies when a chart is opened.
So if max bars in chart is 5000 and you open an M1 chart, after 1 day your chart will have 6440 bars (the original 5000 bars plus 1440 new M1 bars)

The terminal doesn't do a very good job of releasing its resources, and you can't force it to do so except by restarting.
Values of indicators are stored as doubles (8 bytes)... doesn't sound like much, but when you start multiplying timeframes, symbols, indicators and bars on chart together the numbers get big fast!

I'd start by trying to loop all the symbols on one timeframe with one indicator. Then gradually start adding timeframes / indicators and you should get an idea of where it chokes. It could also be something wrong with the code, so use print statements to help debug.

The Ichimoku indicator is a lagging indicator and is useless hence why it's existence is promoted usually by the inexperience onlookers. Your guess or tossing a coin is better then the indicator.

Hi,

Well... i finally managed to get this scanner to work. I've turned the indi into an EA and i attached the EA to an offline chart that has a perpetual fake tick generating script attached to it. Why an EA you might ask? Because the Start() event handler of an EA completely ignores any new incoming ticks as long as it is still processing any given tick. Start() of an indi restarts every time a new tick arrives, doesen't matter if it wasen't ready processing the prior tick, it just restarts and that was what probably contributed to the whole thing choking.

My EA isen't exactly fast though. It takes on average 7 minutes to run one scan cycle of all 216 symbols. When its scanning there is an extremely high load on the CPU. Its so high that i can hardly open any other programs next to the mt4 terminal. If i do the CPU hits its maximum capacity in no time and the EA starts processing very slow. This happens especially when i run a youtube film inside a browser. Then the EA just stops cycling almost completely... Its ridiculous. I feel like i have some optimizing to do. I have some ideas on how to do this but i don't know if implementing those ideas will make any difference. So i would like to ask your opinion on these ideas.

1. Will the scanner indicator run faster when i internalize all the custom indicators by turning them into functions that can be called from within the Scanner indicator itself (instead of using iCustom()) or woulden't that make any difference? In other words: is an external indicator call slower then its internal function call equivalent.

2. Each custom indicator that i call with iCustom() automatically calculates all the possible values for each bar in the history. This is very time consuming because i usually only need a small portion of that data for my further analysis. Usually the most recent datavalues out of the indexbuffer array. The for loop that usually causes this looks like this:
Inserted Code
   if(counted_bars>0) counted_bars--;
   int limit=Bars-counted_bars;
 
   for(i=0; i<=limit; i++)

Imagine that i only need the last 3 most recent values of this indicator for further analysis and the period of previous values this indicator requires to calculate a new value is 15. Would it then suffice to replace the variable limit with the constant 18 (15+3)? Surely that way the indicator will be allot faster when it only has to calculate the last 18 values representing the last 18 bars in a chart. So the code would be:
Inserted Code
   for(i=0; i<=18; i++)
Also, do i still need that counted_bars code when i don;t plan on displaying the output of the indicator under a chart window?

Kind regards,

Codix

Hard to say, but quite possibly. Some of the indicators may be badly coded, for example recalculating every bar every tick. They may also have additional buffers for visuals that you don't need in your application. By making internal functions, you can strip all that out. Sometimes that is practical to do, other times not.

Again, hard to say without seeing the code. But if you are using iCustom you don't normally need to do any loops. The indicator is essentially getting added to the chart and you have access to all the shifts. If you want the last 3 values, just call the shifts directly. Even if those 3 values are based on 15 (or 20, or 100) bars of data.
Let's say I have an indicator called "MyInd" which calculates its values based on the last 15 bars of data, but I'm only interested in the last 3 values. I would make the call like so:
Inserted Code
void OnTimer()
  {
   double MyInd0=iCustom(NULL,0,"MyInd",0,0),
          MyInd1=iCustom(NULL,0,"MyInd",0,1),
          MyInd2=iCustom(NULL,0,"MyInd",0,2);
   if(MyInd0>=MyInd1 && MyInd1<MyInd2)
     {
      Alert("Signal");
     }  
  }

Yes, but on initialization of the called indicator it still calculates all the values for all the bars in the chart of the symbol BEFORE returning you those 3 values. When you're only interested in those 3 values woulden't the indicator initialization become allot faster when it no longer has to calculate all indicator values for all bars in the symbol its analyzing?

Exactly what MT4 does with iCustom isn't documented in detail anywhere I've seen, but it has been discussed on quite a few forums.

From my understanding, once an iCustom call is made that indicator gets attached to the chart (but you don't see it) and it continues to run in the background. The indicator won't keep reinitializing each time you access the buffers through iCustom. When the EA gets removed, the iCustom indicators also get removed.

You used to be able to see this in the logs with Custom Indicator whatever: loaded successfully and Custom Indicator whatever: removed but I don't see that anymore. Maybe MetaQuotes changed the logging method or maybe they changed how iCustom works... IDK

But presuming it still works the same way, the first iCustom call may take some time (as the buffers get populated).

But from then on, a normally-coded indicator should make use of IndicatorCounted() or prev_calculated to only update what is needed.

That is my understanding, but as I said I have not seen any official MetaQuotes publication detailing exactly how the terminal handles iCustom calls.

Happy to be corrected

-- Added --
So, here is how the maths pans out as best as I can tell:
216 symbols x 6 timeframes x 22 indicators x 8 bytes = 228,096 bytes per bar just to store the buffer values (presuming only 1 buffer per indicator).
If you have 5,000 bars, that is 1.14GB RAM.
If you have 20,000 bars, that is 4.56GB RAM.

I believe the terminal limits are 3GB for 32 bit, and 4GB for 64 bit - see here

Hence why I recommend you drop max bars in chart right down low.

They don't happen at the same time since they're generated from different TF(s). This is good because it confirms the trend but would prefer that they are not on top of each other but beside each other. I am therefore wondering whether it is possible to re-code the indicator in a way that if one signal is already there, the next signal will go beside it instead of being on top of the previous signal. Alternatively, is it possible to code the same indicator with the option of having 3 or more TFs and the signals beside each other.

Thank you for your help
