There are 2 check boxes . 1) Default-Off was said for "Generate a new tick with zero volume" " Generate a new tick with zero volume upon DailyHigh (DailyLow) update" is turned OFF by default since MultiCharts 14 Release 2 (if MC has been installed on a new computer or IB settings have been reset). 2...

Thank you Svetlana, With turn OFF Include "Unreportable Last" Trades in IB data feed settings , it has worked well for the past 3 days. May be this should also be default setting , and with documentation that it also solves the block trades inclusion issue, which would not be known by the name and e...

Have unticked the check box "Generate a new tick with zero volume upon DailyHigh (DailyLow) update" , I still see the block trade which is at price-way-off the current bid ask level. priceWayOff.PNG When look in the quote manager, it is seen as one trade with volume of 200 lot at price 65.67 which i...

Hello Ima, Does it help to do via the untick of "Include Unreportable Last Trades" in IB data feed config ? Also, did the off-price trade exist in quotemanger / the symbol row / editData ? Then, if it exists, does the off-price trade disappear after reloading of the symbol via mc reload ? Regards

Explanation to my guess: String is not in the dll-calling keyword so my guess is to change your "String" to lpstr.
Please see the possible list in https://www.multicharts.com/trading-sof ... LL_Calling referenced given by zheka.

Meecc

Hello
my another guess,
also try changing
from String to lpstr
eg.
from
DefineDLLFunc: "swedll64.dll",Long,"swe_calc",Double,Long,Long,Double, String;
to
DefineDLLFunc: "swedll64.dll",Long,"swe_calc",Double,Long,Long,Double, lpstr;

Meecc

Hello, By changing name, is the following the right and "ONLY" place needed to be changed ? ie via quote manager, edit symbol as shown and then change name to some other name. . . changeSymbolName.PNG . . I assume having done above new contracts will replace as the recurring name and we can have the...

Meecc

Hello my guess is to try assigning LongPos[0] to a var and then pass the var to the fn call. var: myvar(0); myvar = LongPos[0]; then change from ret_flag = swe_calc(JuliandayUT, 0, 274, LongPos[0],serr); to ret_flag = swe_calc(JuliandayUT, 0, 274, myvar ,serr); as the fn template is looking for a do...

Meecc

Hello
Array declaration should be in the form of
array: ArrayName[size](initialValue) ;
sth like
array: LongPos[5](0);

Meecc

Given IB futures symbol repeat itself in every 10-year cycle, eg. CLF0 for 2010 will be used for year 2020 as well. Will the new 2020 contract be added to the same symbol in MC database? Will old value in 2010 be auto deleted? Do we have to do kind of export old 2010-section data? Or is it that noth...

Flush "Cached" Data Typo

Meecc

"bowlesj3" I had to create my own wrapper functions in MC to cover off every possible data type that is available with the GVs (boolean, double, integer, float and string).

Hello

UpTicks & DownTicks for the Volume Delta & Cumulative Delta chart types are now available in the code. Learn more: https://www.multicharts.com/pm/viewissu ... no=MC-1437

Any info on the keywords to use

Meecc

You can configure this with the 'Data Server Mode', which can optionally remember the last setting or pop-up each time you start MultiCharts to choose between real-time data (online) or working offline. Thank you very much Josh. I have already had the 'Data Server Mode' setting set as offline, It i...

Further to TJ's suggestion above, "On the offline machine, it must not be connected to the internet" . Once I have the internet disconnected, is there a way to start MC right in offline mode (no real time data), so there will be no window for which to click the "ok" button asking to start MC in offl...

Meecc

TJ,
thank very much for your suggestion,
though it does work, it may not be applicable to all my situations.

Mc Team,
I still would like to know, the details of the keyword
" check_authorization_response ",
be it another way to solve the issue.

Meecc

Where did you find this? Right click on the editor , type "check" What were you trying to do? I would like to use 1 mc license for 1 online and 1 offline machine , but DRM is not checking correctly, sometime , making both online (green). Then, in the middle of nowhere, DRM will disconnect in the onl...

Meecc

Mc team ,

please elaborate on the usage info and the 2 inputs : response and Source
of the key word " check_authorization_response ".

TrueFalse return :
check_authorization_response
( response (NumericSimple) , source (NumericSimple) )

Thank you.

Hello tonyng,
For

Code: Select all

" external: "example.dll", int, "db_SetFXStrategy", IPowerLanguageObject,string,sting;

could try replace IPowerLanguageObject
with IEasyLanguageObject.
So it becomes:

Code: Select all

" external: "example.dll", int, "db_SetFXStrategy", IEasyLanguageObject ,string,sting;
