[MT WS API]

Hello,

Will it be possible to remotely control scanner actions for a portfolio window from API commands?

Start/Stop/Pause scanner

Enum and switch scan

Enum and edit params

Freq etc.

The goal is to daisy chain some scans and may be get filtered results to generate a report.

Thank you.

 

[API QUESTRADE]

I use Questrade and MT handles all the heavy lifting. After adding Questrade under Trade/Account once, I only have to login to Questrade account every once in a while.

[API connection issue]

ah ok, same problem as last time. 😌I'll go through my command syntax again.

Thank you Jerry

[API connection issue]

Hello👋

Not sure if there has been a recent change but I'm seeing intermittent error on sending commands. Following are tested on my app as well as WSTester.exe.

Socket connection opens but fails to connect with password. I now see in logs <******> instead of plain password when it fails. But WSTester or my app are sending all commands as usual.

[API access to chart period displayed?]

Jason, I don't know if I fully I understand your use case but here's something you can try to read a chart's frequency from WS API.

Calculate CandleSizeInSec function's value in a Painbar to assign frequency to chartvar() or Intervar(). Set this paintbar on the chart then value read from your app from getintervar()

[WS API - No response]

Thank you Jerry

[WS API - No response]

Hello, I am not seeing response from MT except Connect command. Following is from WSAPI Tester: What is "no cmd in message"?

MT: 11:46:21.66385 27048: API_WS: RECEIVING (6767054c-0): 00019: {"Cmd":"enumPorts"}
MT: 11:46:21.66785 43344: API_WS: no cmd in message: {"Cmd":"enumPorts"}

[other symbol data]

I see following in Beta 9880.100.

1. ADDED - PAINTBARS/SCANS - Ability to reference other symbol data. NOTE: Calculations are only triggered by primary symbol's changes, not secondary one

Can you tell which function is it?

[Scan Paintbar advanced mode questions]

Hello Mike,

I am now using Set/GetInterVar between MT and my WS-API app to exchange data. Can you tell me if it should work like data subscription? Within MT GetIntervar can stream between two scans. Do I need to do something on app for something similar?

Also, is there a way to throttle a scan, say one scan pass over all symbols then wait n seconds before going again. Or if frequency on portfolio is set to 5 minutes thena rule to run scan every (frequency * 0.25) minutes.

Thank you.

[Scan Paintbar advanced mode questions]

Is there a safe way to ready/write into to text (non-code csv) file from scans?

Error:
24, 19    CS0103    Possible security violation  

 

 

[Scan Paintbar advanced mode questions]

Thank you, CandleSizeInSec works good for intraday. But on historical it returns following:

1Day=60

1week=300 so on..

Not sure if this is expected.

[Scan Paintbar advanced mode questions]

If it's not possible or too complicated then no worries. I am able to use DefinedPaintbarParameter and enter frequency identifier manually for each scan window.

[Scan Paintbar advanced mode questions]

Hello Mike, thanks for this info, I'll try it out. I assume if there are any variables in external script requiring access to data will have to be added to internal paintbar code?

The other question I have is about scan chart parameters such as frequency can be read from within a scan?

I want to append this to naming SetInterVar() then call by GetInterVar() elsewhere based on frequency selected.

[Scan Paintbar advanced mode questions]

Can you share an example external file and how it used within a scan? What type of code or languages are compatible?

Including External Code
#include	This allows you to include code from an external file (specified following the #include).   Example:   #include c:\temp\mylibrary.code

 

[Some symbols stop streaming]

I sent you log, I did not see a symbol limit pop up in MT or TWS. If there was an error, it never recovered despite deleting symbols and restarting MT.

I'll check again tomorrow.

[Some symbols stop streaming]

I have 26 symbols in MT in two portfolios, both using IB data feed. I noticed this morning, AAPL, AMD and SPY stopped streaming. After clearing data and backfill, I got AMD back to normal. But AAPL is still not streaming, SPY streaming Last price but no bid/ask. Also, it backfilled only current day for Intraday.

I am on 9810.100, is there a known issue like this? Other symbols are streaming ok.

[Incorrect Level 1 values]

Thanks for clarifying your formula. Mine was based on my understanding of description of this column in MT help docs. i.e. Range as % of price.

The formula you shared is similar to IV rank formula, but for price.

[Incorrect Level 1 values]

The calculation is slightly different with each data feed, but that's due to it's feed's speed.

Here's actual example with IB:

Symbol    AAPL  Last    136.50 Low  133.73    High 137.65        Rng    3.92    Rng % 70.66326531

I calculated below for same data feed.

SetScanResultColumnName(0,"Range%");
SetScanResult(0,((SymbolData.High - SymbolData.Low) * 100 / SymbolData.Last));

Range%    2.871795

[Incorrect Level 1 values]

Hello,

Can you check if Range% values for Day/52W are correct in columns? They seem too high for Day and too low for 52 week.

Thanks.

[Near the money # of contracts]

Thank you

[Near the money # of contracts]

Hello,

There's an option chains setting to display number of contracts near the money which is minimum 3. Can this be reduced to just 1?

Thank you.

[Number 7 key map issue on numpad]

Num lock was on, I figured out the issue. I had 7 assigned to a custom hotkey. In chart and trade ticket, it was calling the hotkey instead of number when typing price or quantity.

[Number 7 key map issue on numpad]

Hello,

Number 7 key on number pad does not send 7 in some situations.

On trade ticket, it send Home.

On chart, I use 7 for 200 bars shortcut but it only changes the number in drop down, does not change the bar on chart. I have to use number line of keyboard.

Also non-urgent issue, on the option risk analysis, toggle buy/sell or call/put messes up the graph view. Starts to show opposite direction of chosen.

 

[Sub-layouts or Window grouping]

Since MT doesn't have window work spaces or tabs, I would like to suggest following that hopefully can be implemented easily.

Sub-Layout: From MT Dashboard > Windows tab, user selects required windows with CTRL+Click then Right click to save as a sub-layout. This sub-layout can be used to open all the windows in this group.

User can CTRL+Click items in the Dashboard > Windows as assign a Window group colour or name for easy  window management e.g Minimize/Restore/Close/Move/Lock that apply to all windows in the group. MT currently have a feature to Shift + Arrow to select windows then minimize/Restore them.

[Portfolio totals / sub totals]

Thank for adding the columns and scan data points for options. You guys rock. 🚀💯
