way to get multiple buffer values with single iCustom call?

  • #1
  • First Post: May 9, 2020 4:02pm May 9, 2020 4:02pm
I have a indicator with 8 buffers... Is there a way to call the indicator with iCustom--- and have the call pull all 8 buffer values in 1 pull....

it would be cool if there was something like iCustom(NULL,0,"name",input,input,BFR1/SHIFT,BFR2/SHIFT,BFR3/SHIFT);

Or-- is there a way to run the indicator from the EA-- then from the EA-- go into the indicator buffer array and pull the needed values? This way only running the indicator once yet able to get all 8 values...

No, there is no way... You have to call iCustom() 8 times to read all 8 buffers.

MathTrader7 is right but there is no reason to suggest changes in the language. Functions allow you to encapsulate functionality and you can return as many iCustom() values as you wish from a single function call.

Side effect: If you use iCustom() as shown your custom indicator will not be calculated 8 times. It's still loaded and calculated only once and the above multiple values version is as fast as returning a single value. There's a very small difference, so small that it's almost not measurable.

Emmzett... So if i understand this right-----your solution would be to get multiple values from each buffer at one time... correct?
So for buffer 0--i could get val1,val2,val3 all with one call...

What im trying to do is just get the current value from each buffer-- but with only one call to the indicator..

so-- iCustom(symbol,name,buffer1/val1,buffer2/val1,buffer3/val1).... Im thinking your solution wouldnt work for this scenario -- correct?

It's exactly for that. You get all buffer values for a single bar offset. In the case of my example that's 8 buffers but you are free to code whatever you need.

But arnt you calling the iCustom call 8 times (for 8 buffers)?... That is what im trying to avoid.... Id like to call the indicator 1x and retrieve all 8 buffer values with the one call....

Read my first post in this thread again. I recommend to get familiar with the term encapsulation and study programming concepts, i.e. functional and also OO concepts. What you really want to avoid is recalculating your indicator for each fetched buffer/bar.

That is what i am trying to do-- avoid recalculating the entire indicator for each buffer value im trying to get.. My indicator has 8 buffers... Id like to be able to get all 8 buffer values from ONE call of the indicator... Your function above calls the indicator 8x... That is what im trying to avoid... Id like to call the indicator once--- and retrieve buffer 1-8 altogether... I know how to write a function that calls the indicator 8x with one function call... Thats not why im trying to achieve here..

Use the code as I have written and if you believe your indicator is re-calculated 8 times put a debug statement - or Print() - into OnCalculate() of the called indicator. You will find it's called only once for each incoming tick.

Calling iCustom() doesn't mean recalculation of the indicator. It just fetches a buffer value.

emmzett, pls help me.

I got stuck in this part

https://www.forexfactory.com/thread/...6#post13775516
Do you have the solution for the issue with iCustom() on indicator trade_confirmation.ex4, how can it get its buffers correctly

I have tried with
all the parameters filled and non parameters filled so it should pick deault, add to the end with for buffers reading
(...,0,3,0)
(...,1,3,0)
(...,2,3,0)
(...,3,3,0)
with
(...,1,0,0,0,0)
(...,0,1,0,0,0)
(...,0,0,1,0,0)
(...,0,0,0,1,0)
and with
(...,1,0,0,0,1)
(...,0,1,0,0,1)
(...,0,0,1,0,1)
(...,0,0,0,1,1)
what else you can try?

...what else you can try?...
A few ideas:

1st example: You always read the same buffer (3) and the same bar offset (0). No surprise that it doesn't work.
2nd example: Almost the same mistake as in (1). You read the same buffer 3 times.
3rd example: Again you read the same buffer 3 times. This time you read bar offset 1.

Probably (a guess, I do not know!) it makes no sense to read bar offset 0 (the current bar). You should only read finished bars (at least offset 1).

Attached the correct call of that trade-confirmation indicator. Adjust it to your needs. Again, don't read bar offset 0, it makes no sense.

with V 0.3 in tester. I think the trial run is abnormal, it takes very long until the indicator loaded in the chart, then the simulation did not run, like a normal tester run, even after 5 min waiting

Again your iCustom() usage is wrong. Your code:
Inserted Code
double upArrow1   = iCustom(NULL, PERIOD_CURRENT, "Trade-Confirmed-Indicator",1,4,1);
double downArrow1 = iCustom(NULL, PERIOD_CURRENT, "Trade-Confirmed-Indicator",2,4,1);
double upArrow2   = iCustom(NULL, PERIOD_CURRENT, "Trade-Confirmed-Indicator",3,4,1);
double downArrow2 = iCustom(NULL, PERIOD_CURRENT, "Trade-Confirmed-Indicator",4,4,1);

Quoting ntk
...but why the all arrow values are the same...
Because in all 4 calls you request the same buffer (next to last parameter = 4) and the same bar offset (last parameter = 1). So the result will always be the same.
Requesting buffer 4 is wrong anyway, as there is no data assigned to that buffer. The developer set it to -1. It's useless for you. There are only 4 buffers (numbered from 0 to 3) for you. It seems you don't yet understand functions, function parameters and/or the documentation of iCustom(). Unfortunately I can't help you with this.

You have to call the indicator the way I showed you in the file I attached in my former post. No way around that. And the first parameter after "Trade-Confirmed-Indicator" is CountBars which needs to be at least 100 or so.
It takes blood, sweat and enough tears to wash away the blood.

with 0.2 I assume every thing is set, I just get the missing bits so it is compiled, run it then iCustom() deliver arrow values

simulation load the by iCustom() called indicators in 2 sec, then I see the simulation uning on chart as expected

Is this the correct run, what iCustom supposed to do? What is your eveluation? I still dont get all the 4 arows values to be sure they dont be garbage; perhaps I use on wrong market or not run long enough, M15 and I look back 100 bars only

...Is this the correct run, what iCustom supposed to do?
Yes, looks valid to me. I don't know the inner operations of that indicator, so I can't tell you when and how the arrows show up. You have to check the indicator in the tester. I don't even know if it can be used in the tester as it fetches current data from the internet (with a web request). Of course such a web request will most propably produce unexpected results in tester. You have to ask the developer for this.
It takes blood, sweat and enough tears to wash away the blood.

now run test on GU I got 4 arrows. I did add the trade_confirrmation indi also to the chart, to see where the signal, appeared and the simulator also delivers the arrow's values from iCustom()

I think this is the correct read of arrow values from iCustom(). The othe eperiment simulation take long to load indis on chart hen not run simul at all because iCustom() ran into a loop, or exception somewhere

I see also Pzelopetrend is rubbish to be used as trend indicator it repainted, may be I tr Non lag dot, hull, supertrend or half trend
What would your evaluation says?


How did you get out the whole structure how trade_confirmation.ex4 should be called correctly by iCustom? I save setting then use the setting to fill values in iCustom() but with that method still missing a few elements ...
