MultiCharts: Trading Software for Automated Trading and Backtesting

RWDickinson

Thanks, JoshM, but I have now tried your suggestion and the two indicators still are nowhere close to matching. I have no idea how to proceed.

RWDickinson

Background: I have two (#contracts) charts of the same data, one at coarse resolution, one at finer resolution. I have indicators on the two charts that I have been trying to correlate "by eye" so I wanted to combine them on a single chart window so I could put the two indicators on the same scale. ...

RWDickinson

Well, I've given up (as with several other problems w/ MC). Sometimes I get the error message, sometimes the code runs and symbols show up momentarily then disappear, sometimes the code runs but no symbols appear at all. I did find on a previous problem that text drawn on the last bar on chart will ...

RWDickinson

TL_Exist(), Arw_Exist(), Text_Exist() do not exist (in the help screens).
I'll try them anyway.

Text_Exist() does exist (study compiles)
Arw_Exist() does not exist (study does not compile)

So I'm still using ...Id <> 0 for arrows.

RWDickinson

Well, I'm not using TL (that was ABC who thought there might be a connection), but I take it this applies to my use of Arw and Text, also. I'll check it out.

RWDickinson

Maybe this helps you in fixing your study or it helps MC in tracking down the issue. Thanks for the tip. I just tried "if ...Id = 0 ..... Print("Error message");" for each of my elements. Still get MC error as above, and did not get my error message in the output window. Do we know whether user-pri...

RWDickinson, please post the code of the RD_ScreenVPos function. yep, here. ------------ code ------------ {RD_ScreenVPos returns a price value that lies at the given %age of screen vertical space. i.e. 0% lies at bottom of screen, 100% lies at top of Screen } Inputs: Percentage(NumericSimple); //0...

your study requests a detaseries number/index that does not exist on your chart

Well, the keyword "data" (as in data2) does not appear in the study. Is there another way to "request" a data series?

RWDickinson

So I take it nobody is able to tell me what the error message means . The study is my own code, and somewhat long. I'll copy it in full, since I have no way of determining in what portion the supposed error occurs (and since I can only attach one file). ---------------- code -------------------- {cr...

RWDickinson

Error message appears when I activate a particular compiled study. There is data in the price chart that this study references.
I have no idea what this error message is trying to tell me. Can someone translate for me, so that I can try to fix the problem?

RWDickinson

The new barnumber capability for arrows, text, and trendlines is great.
However, for arrows and text, we need either SetValue(id,value) or
SetLocation_bn(id,bar#,value) or both. Currently not possible to set
a (vertical) value on existing arrows or text except by date/time.

RWDickinson

RWDickinson,

Please go to Window->enable the option Show detached windows in inactive workspaces.

Ha! new option. I looked for something like this but didn't find it. Thanks.

RWDickinson

Just converted to MC64. There is a difference (compared to 32-bit) in handling detached charts. 32-bit: can have detached charts from multiple workspaces on the desktop simultaneously. 64-bit: detached chart(s) from only one workspace appear on desktop at a time. Detached chart(s) from workspaces th...

How is the !From Broker To Strategy MP Synchronizer! strategy intended to be used? Should we copy the code into our own exit strategy? What are the Timeout and Latency inputs for? If we only need to synch at the end of a bar, is all this needed?

RWDickinson

I have a continuous future symbol that I build manually by exporting current data from current month and importing that data into my continuous future. When I do the export, volume column header is "TotalVolume". Import is unable to understand this header, so interprets it as "Down Volume"; I have t...

I am posting an indicator that detects regular divergence between the price and MACD. Just insert it onto your chart, then insert it again and change the plotseries to 2 ( this will then display the MACD itself with Trendlines ). I know this is an old thread, but in case anyone else picks this up, ...

JoshM wrote: Meaning that another program can read the global variables as set by MultiCharts? That's quite interesting. Do you perhaps know of any examples or references about this? Google searching didn't turn up anything. [edited version] Josh, I didn't think another program would be able to acce...

RWDickinson

OK. Hmm, second data series does not use my edited (default) session info even when I select Session: Default?

Anyway, that's a different problem. Thanks for your help on this one.
I was indeed trying to use the Add button.

RWDickinson

Thanks, TJ. But I'm still missing something basic. Say for now, that I want a second plot of the same symbol on a different time frame. I right click on the chart. There is no Insert Instrument , I take it you meant Insert Symbol . If I add the same symbol from the list, I get a dialog box that says...

RWDickinson

There are many articles in the forum about using data1, data2, etc. However, I have a very basic question: how do I create a chart with two (or more) symbols? The help seems to indicate that this is only for strategy use, and in any case I couldn't follow the help instructions. How do I create the s...

RWDickinson

Ignored ??!!!!?? Can I possibly be understanding you? "MarketPosition[1]" is the same as "MarketPosition"? And somebody thought that was an improvement over compiler complaints about "MarketPosition[1]"? Tell me it ain't so, Joe!

RWDickinson

A question I can't seem to answer from the docs: Using MC 4.0. I have a dynamic array of numeric values. How do I add a new value to the array? Do I have to keep track of the current "end" number and assign to "end+1"? or can I create a new element at 0 so that the latest entry is [0] and the next b...

RWDickinson

Not quite sure I understand your question, but you can do anything with an indicator number that you could do with, say, close. Of course an "indicator" (in PL-speak) is a display, not a function, and cannot be called in order to get the value; but in most cases the indicators call similarly-named f...

RWDickinson

I'm probably missing something basic here. I am using a pyramiding scheme: <i> if longCondition1 then buy("L01") 1 contract next bar market; ...... if longCondition2 then buy("L02") 1 contract next bar market; ...... etc. </i> Each entry is a single contract. This works fine. At some point I am long...

RWDickinson

Ah, yes. Now I see it Marina. I was looking under "Date and Time Routines" (silly me - how obvious that it would not be there!).

RWDickinson

OK, knowing the parameters that are triggering the error, I guess I need to use the print-statement method to find out where that error is occurring? Wow, I guess I've been spoiled by real languages (you know, the kind that give you real error messages). Oh, well.

RWDickinson

I have no information about Transact, but I do know from painful experience that "unfiltered" data from the exchanges have many error ticks in them. "Filtering" (the thing you despise) is what corrects those errors. I don't know where you got the idea that "unfiltered" is higher quality than "filter...

RWDickinson

This question has probably been asked before, but I couldn't find it. I am getting an error message occasionally when I run [Optimize], but never when I put specific values into [Format]. Error is: "Error in study <study_name>: {EXCEPTION} Floating-point invalid operation". I assume this is a divide...

RWDickinson

drwar: First, you would have to give me some reason other than you word for it that the barstatus function can be called from some contexts and not others. That would make PL such a strange language that I would totally give up on ever using it. The documentation makes no such claim that I can find....

RWDickinson

I just modified my original post to add the output results, so that people don't have to run the example to see what its results are. There's only about 20 lines of code total here, and several of those are print statements.

RWDickinson

Drwar, are you saying that barstatus does not work in top-level code and has to be coded in the called function? Or are you just pointing out the typo 'barstatu' in rsi77's code? The latter is fine, I ignored the typo and assumed he meant 'barstatus'. The former would just astound me and cause me to...

RWDickinson

In both of those help files for my version (3.1), time_s is undocumented.

RWDickinson

No, initial value is set only once and variable values set by the script are persistent across multiple executions - if code is executed only once per bar (update on every tick is off). If code is 'update on every tick' then the intra-bar values are screwy (IMO) but MC is implementing the EL languag...

RWDickinson

********* update ********* Ah! time_s, which is the answer to original question, was not in the list pasted into the answer by support, and is not documented in the Dictionary of the PLEditor. And is not in the MC 3.1 help file. *********** original post *********** Am I missing something? The origi...

RWDickinson

TJ: there is no difference in the result; the reason some programmers do this is that in some languages you can avoid some programmer errors by doing your comparisons this way. In 'C' language it is a common error to code "if x = 0" (an assignment of value: assigns 0 and the 'if' will always be fals...

RWDickinson

Sorry, I'm not understanding your question. How is what you described different than having an initial value in an Inputs: statement and then updating it in the script?

RWDickinson

Thanks. In this very simple demo, I don't store the result from the function call anywhere, so there are no variables in the caller dependent on the value returned from the function (at least I think that's what you meant). All of the code is now guarded by "if barstatus=2" so state machine function...

RWDickinson

I want to code a simple state machine in a called function, and use that state machine in a signal. The state machine accepts a "context" input that tells what part of the state machine should be updated. My problem: since the function is called under various conditions, it sometimes gets called twi...

RWDickinson

Thanks, TJ. My question is more like: Vars: abc (0); <code.......> if abc < something then begin ..... end; under some other condition begin abc = something end I need the value of abc to be persistent across multiple runs of the program, i.e. after i set the value during one bar, it must have the s...

RWDickinson

I am having a problem with variables being randomly reset by MC between entries to my code (i.e. between bars). I thought all variables were persistent, but it seems not. The variables I use need to be persistent only within a single indicator or strategy, not sharing among strategies (I think this ...

TY, VM

Sorry, TSS Knowledgebase? I don't know where to find that....

RWDickinson

Pardon a question from a newbie: what is this DTI indicator and where did it come from? Is this the S&P Diversified Trends Indicator? Where did you get the indicator code?
The optimized inverted method looks promising.
