@gsmtricks said in How to include library?:

{"api":"online","appid":"11111"}

Thank you for help.
Feel stupid:

So let me provide full information.

1. I have variable created and named: test_json ( for example )
2. In some time I write there JSON data: {"api":"online","appid":"11111"}

What do I need:

1. Read JSON string from a variable test_json ( here is data: {"api":"online","appid":"11111"} )
2. Save to variable test_status: online
3. Save to variable test_appid: 11111

That all.
If someone can provide me working custom mql code for FxDremma I will be able to use it as an example for my strategy,

@miro1360
With your file JAson.mqh I can do include now.
Now still to understand how to adopt custom qml code.
I have a code:
// Object
CJAVal json;

// Load in and deserialize the data
json.Deserialize(data);

// Try to access the data elements
Alert(json["orderid"].ToInt());
Alert(json["ordercurrency"].ToStr());

But with this code can't compile.
Please advice.

I just need to read JSON string from variable: data

It's not working. Good idea but not works.
How to test?

1. Create new MT5 expert - just empty
2. Export mq5 code
3. Open exported code in MetaEditor
4. Compile it - works
5. Add line #include <JAson.mqh>;
6. Compile - can't compile it. 100 errors.

I know how to do it with native MQL and it works. WIth FxDremma it's not working.

@trader-philipps
Yes, sure I have it done.
You can try your self. Open any Expert generated by FxDreema and try to add line:
#include <JAson.mqh>

You will see - no way to compile it after that.

Did you copy the mqh file in the include folder of your mt4 instance?

• Yes, also just for test i have create some example:

}

}
//+------------------------------------------------------------------+

//+------------------------------------------------------------------+

{
//---

}
//+------------------------------------------------------------------+
//| Timer function |
//+------------------------------------------------------------------+
void OnTimer()
{
// Object
CJAVal json;

// Load in and deserialize the data
json.Deserialize(data);

// Try to access the data elements
Alert(json["orderid"].ToInt());
Alert(json["ordercurrency"].ToStr());

}
//+------------------------------------------------------------------+

I can compile it and it works.

Additionally set project properties to.point to your mt instance.

• what do you mean? As I can see error comes from FxDremma.

I did another test:

1. Downloaded blank expert advisor in mq5 format generated by FxDremma
2. Opened it in editor - compile - works
3. Added same line of code: #include <JAson.mqh>
4. Compile - a lot of error and as a result - can't compile it.

Here is a working example, the question is how to include an external library?

But this example can't compile.

Broker integration I do mean that I have NODE.js app which can connect to binary.com and open trades.
This local APP can send answers from broker to MT and now i can save the WEBrequest answer into a variable as a text string. But this is not useful for me, I need to get the answer parsed

Hi all,

I am trying to make a trading bot with Broker integration.
Right now have Node.js local server which gets a request from MT5 and sends requests via API to Broker.
Right now have a major problem to analyze responses.

The question is:
How i can store WebRequest response into variables?
Here is an example of a response to my request:
{"balance":5704.45,"currency":"USD","id":"548853a0-0bec-a46d-dc34-7cd3f9xxx","loginid":"VRTC15912xx"}

Looking for a way to store array separated into the variables, like:
balance=5700
currency=USD
id= etc,.

Please advice.

It there any way to predefine few payloads for conditions and just choose one of them while initializing advisor?
Default indicators from a platform have that options

Thx for answer, i am done with loop on this

When i store some indicator value into variable ( for example Accelerator Oscilator )., and then print it i see number like:
-7E.08-05 But when i hover on Terminal - i see value like: 0.0005678
So how to get the normal value like: 0.0005678 ??? Coz i need to operate with that numbers...

Is there any way to find lowest and highest value from indicator during x-candles and get this valuse + candle ID?
For example Accelerator Oscillator i need to find lowest and highest valuse during up to 10 candles back.

0 - is candle 0
1 - the lowest value I need to find it and get the value of AO and Candle ID
2 - Highest value I need to find it and get the value of AO and Candle ID

Is it possible to use CURL requests etc?
I am trying to make a trading bot for crypt exchanges. It must work via API.
For example
https://api.hitbtc.com/#trading
curl -X GET -u "ff20f250a7b3a414781d1abe11cd8cee:fb453577d11294359058a9ae13c94713"
"https://api.hitbtc.com/api/2/trading/balance"
The above command returns JSON structured like this:

[
  {
    "currency": "ETH",
    "available": "10.000000000",
    "reserved": "0.560000000"
  },
  {
    "currency": "BTC",
    "available": "0.010205869",
    "reserved": "0"
  }
]

Is there ant way to do it? To send this kind of requests?

@fxdreema said in Combine variables:

In a text (string) field, when you want to use variables, add ""+ in the beginning and + "" at the end. Something like this:

"" + "Buy " + MyVariable + ""

By the way I didn't made this "hack" intentionally. Long time ago I just found out that it works this way and I was doing it like that since then. But if you are not doing it that way, it could not work properly. Make sure that you have ""+ in the beginning and + "" at the end.

I tried but not works for me.
I have Variable: low_ask ( value for example inside is: BTCUSD )

I created a Draw text, and put the code inside:

"" + "Buy " + low_ask + ""

When try to compile:
'low_ask' - undeclared identifier

I wanted to get:

Buy BTCUSD

But still not lucky on this.

After some test i have more info, if

"" + MyVariabe + ""

is my CONSTANT - than it works, but it's not a constant - it is variable

https://fxdreema.com/shared/zMKRcFlTd

I try ti start with trend lines...
But there 2 problems:

1. For 100 candles there a lot of blocks need to do
2. If i am going to change timeframe - it looks broken, is there any way to make it work correctly with all timeframes?

Waiting for help, thx.

@drayzen said in Draw line chart?:

Hi @gsmtricks ,
Would Trace do what you're after?
https://fxdreema.com/examples#Tips-and Tricks

It's very close to trace, just there is no history. For me is good to make a lines between candles, for example latest 100 candles ( close param )

I mean candle has last price, so i am just need to draw lines ( history also )
between candles, similar to line chart or even same.
My idea is to put few assests on one chart.
