  Django Signals Dashboard

Posted by: Hassam

Forum: Algorithmic Trading With Python
- Replies (2)

In this project, I will built a Django Dashboard that is connected with MT4 and MT5. I will post signals on Django Dashboard. MT4 SignalsEA and MT5 SignalsEA will read these signals and open and closed trades on MT4 and MT5 and in return inform Django that the signals have been successfully copied or their was an error. This Django Dashboard front end will be in React. So I will be easily able to open it on my mobile phone. The idea is the use the mobile phone to open and close signals and monitor multiple MT4 and MT5 accounts that can be upto 50-100. First I created SignalDashboard project folder and then I create a backend folder in it and from this folder I launched virtual environment:

python -m venv venv
.\venv\Scripts\activate

First I install virtual environment and then I activated it. Now create a text file in SignalDashboard/bankend folder and add:
Django==4.0

Now install Django:
pip install -r requirements.txt

Now create the backend project:
django-admin startproject backend .

For now we will be using sqlite3. Run migrations:
python manage.py migrate

Install Django Rest Framework:
pip install djangorestframework

Now create the signals app:
python manage.py startapp signals

These are useful shell commands
# python manage.py dbshell
#python manage.py flush
#PRAGMA table_info(SignalEA_signalea);
#python manage.py shell
#python manage.py makemigrations
#python manage.py migrate
#python manage.py runserver
#python manage.py startapp Signal
#python manage.py validate

Create an app signals within the backend folder.
python manage.py startapp signals
Now define the model in model.py of the signals and then enter that in admin.py and make entry in the backend settings.py telling about the restframework and signals app.
admin.site.register(Signal)

You also need to tell urls.py in backend to check urls.py in signals app.
path('signals/', include('signals.urls')

Then you have to make serializers.py file in signals app and make a serializers class. After that you have views .py.

Now I made the models. One is Signal. I have generated this JSON object when running the server on localhost:

http://127.0.0.1:8000/signals/signals?format=json
{"signals":[{"id":1,"signal":"buylimit\r\nGBPUSD\r\n240\r\n1\r\n0\r\n3\r\n2\r\nLiteFinance"},{"id":2,"signal":"selllimit\r\nEURUSD\r\n240\r\n0\r\n0\r\n3\r\n1"},{"id":3,"signal":"selllimit\r\nEURNZD\r\n240\r\n2\r\n0\r\n3\r\n1"}]}

  MQL4 Script to read the Margin and Spread for a Currency Pair

Posted by: Hassam
04-22-2023, 01:43 PM
Forum: MQL4
- No Replies

Before you open a trade, you need to have the amount greater than the margin required for trading that currency pair. Below is  the MQL4 script that you can use to easily check the margin required for that currency pair and the spread for that currency pair:

Code:
//+------------------------------------------------------------------+
//|                                                       Margin.mq4 |
//|                                                     Ahmad Hassam |

//+------------------------------------------------------------------+
#property copyright "Ahmad Hassam"
#property link      "https://www.doubledoji.com"
#property version   "1.00"
#property strict
//+------------------------------------------------------------------+
//| Script program start function                                    |
//+------------------------------------------------------------------+
void OnStart()
  {
//---
   Print("Symbol=",Symbol());
   
   
   Print("Spread value in points=",MarketInfo(Symbol(),MODE_SPREAD));
   
   
   Print("Free margin required to open 1 lot for buying=",MarketInfo(Symbol(),MODE_MARGINREQUIRED));
   
  }
//+------------------------------------------------------------------+
As you can see above this is a simple MQL4 script that uses an inbuilt MQL4 function that checks the spread and another function that checks the margin required.

  MACD_Color Indicator MQL5 Code

Forum: MQL5
- Replies (1)

I use MACD a lot in my trading. I use MACD as a momentum indicator. I need to now when the momentum is becoming strong and when the momentum is becoming weak. The default MACD indicator provided on MT5 has no color. So I have coded a new indicator that uses the default MT5 MACD indicator and colors the bar. When the momentum is strong in up direction it will color the bar as green and when the momentum is strong in the down direction it will color the bar in red. When the momentum increase and the MACD is below zero the bar will be light green and when the momentum increases and MACD is above zero, the bar will be dark green. In the same manner, when the momentum increases in down direction the MACD is above zero, bar color will be light red and when momentum increases in down direction and MACD is below zero, bar color will be dark red. Below is the MQL5 code for this MACD_Color Indicator:

Code:
//+------------------------------------------------------------------+
//|                                                   MACD_Color.mq5 |

Star Conditional Scoring and Ranking Program in Python

Hallo Sir!

It can be hard , time consuming sometimes to manually look at each currency pair and look for trading opportunities ,especially in short term trading.
Sometimes it can make someone to loose opportunities because 'you were too late' or sometimes one can be tired or have a bad day and won't analyze properly which leads to losing trades. Sometimes someone wants to focus only on Major pairs meanwhile there is much greater opportunity on Exotic pairs and the person doesn't know.

I think there could be a solution to that problem called Scoring and Ranking System based on some predefined evaluated conditions.
I believe such basic system would make it easier to avoid loosing opportunities , would save time and could help to filter out more potential trades which could be more accurate.

Could you teach me how to build such Program in Python that as a result would screen and filter out pairs that are most likely to increase/decrease in price OR to be more precise , screen the potential for trading opportunities based on predefined concepts ,before taking a position in the market?

This question is on my mind very much... 

Is it a good idea to create currency strength meter and then apply and fit a linear model (as indicator) around this single currency strength and use it in actual trading to predict price/path from that individual currency strength?

As you agreed with me that pattern does not mean the well known chart patterns. Patterns means time series patterns that have some statistical property that can be measured.

Can you teach me how to extract and interpret useful information/patterns from time series with some statistical measurable property for trading?

Are there good techniques for setting small stop loss ratio to reward in order not to get stopped out easily?

Imagine i start with 1000 dollar account and i risk 1 % for a trade which is 10 dollar and i want to make 200 dollar ratio reward.

Most of time i would get stopped out easily by the market with such tight stop loss or if my lot size is bigger but still its not excessing the 1 % risk ratio.
How to handle such issue? what are good entry techniques to such low risk strategy that you recommend to play?
