cAlgo Programming language (cTrader platforms)

any one has a great experience in this field could share us his applications.
this language is a C# language.
so if your are familiar with C# , almost you can design any auto trading strategy.

the following may be good resources:
https://clickalgo.com/ctrader-algorithmic-trading-school
https://www.bitdegree.org/course/ctrader

There are 2 main titles:
1- cBots ---- corresponds to experts in mt4.
2-Indicators -- corresponds to Iindicators in mt4.

cAlgo IDE Editor:
-cTrader platform provides "Automate code editor" to build either anyany cBot or Indicator

cBots:
There are three main method (driver methods)

1-protected override void OnStart()
2-protected override void OnTick()
3-protected override void OnStop()
also there is a fourth method named OnBar();

but the template is the first three methods (see picture)

OnStart is suitable for initialization or for putting orders one time only, etc . .
OnTick is the appropriate place to put your strategy logic.
Onstop: works when removing the expert "cBot" and is the perfect space for deinitialization.

Indicators:
There are two main methods:
1-protected override void Initialize()
2-public override void Calculate(int index)

Q1-From where you can download and install trading cTrader Platform?
Q2-How to open terminal?
Q3-where you can find cBot Editor from within the terminal?
Q4: How to compile your cBot code?
Q5 - how you can run your cBot on EURUSD for example?

all these questions will be answered in short sufficient clear manner.

now we must have simple task to know in advance just for educational purposes. let us say method: ExecuteMarketOrder
this method is used for opening orders either market or pending.

I just want to open market buy order on GBP.JPY , amount 10000 GBP, with label "ForexFactory-1" and order comment is "Yassine and N. Yala. are my best friends"
StopLoss and TakeProfit will be left 0.00
i just need Start() method.

thererfore we need method # 4 from the last post's picture.

instrument name is determined during runtime process not in compiling-time.
this is a great feaure

Q1-From where you can download and install trading cTrader Platform? try spotewqre site or any broker offereing cTrader platform, like fxpro.
Q2-How to open terminal? try it your self--like any other application.
Q3-where you can find cBot Editor from within the terminal?
Ans: to open cBot editor called "Automate code editor", from terminal double click "automate"

then do the following 5 steps
1-click cBot bar
2- then new
3- then write your code (add your logic to the default template)
4-then save it
5-then compile it
6-then check compilation results

if matters go fine, now its is available for running for any instrument you prefer.

how to apply it to chart?
it is very simple
from editor page in front of your cBot C# name, click on plus sign "+"
"+" is "add an instance"
that mean take a copy of it to EURUSD for example
and later you may take another copy to AUDUSD
and so on
hence word "instance"

when you click on + sign a list of symbol names will appear, select any instrument.
you can select only on instrument -- that is the meaning of "instance"
we select GBPUSD.

double-click on GBPUSD

LASYT POST = YOU ALREADY APPLY IT TO GBPUSD CHART.
the chart will be opened immediately as follows: with blue sky arrow "cBot waiting to start it"

click on Bot starter--it is color will be brown:
and now it is working correctly.

just to gain more confidence in yourself, try minor-applications "one-task cBots"
for example: just to open market order
or to print only a message in console
etc...

example-1:
we want to print "السلام عليكم ورحمة الله وبركاته" in message panel "log"

left: editor
right-cTrader platform

try to hundreds of minor tasks.

example-2:
we want to place pending sell order on USDJPY at price 112.05 with volume of 5,000 USD
for pending limit orders (that mean either BUYLIMIT or SELLLIMIT)
we use build-in method named PlaceLimitOrder(arguments)
cBot API syntax
public TradeResult PlaceLimitOrder(TradeType tradeType, string symbolName, double volume, double targetPrice)
there are 7 methods named PlaceLimitOrder.
same name but with different arguments.

we select here the shortest one with 4 arguments (trade type, symbol, volume, entryprice)

The Output of the program is: pending sell limit order on USDJPY at price 112.05 with volume 5,000 USD

LOOK:

TradeResult is the declaration type(return type) of PlaceLimitOrder method.
it is a strange type, but its return type is either true or false = does the order ha been placed successfully or there are some errors??

and since it is a strange type (not primitive type like integer or double or long or string or Boolean etc..) then it should be a Class
this class named TradeResult extends the superclass of all classes "Class Object"

and as its name implies "TradeResult", it is intended for trading operations.
it has many properties and methods (in Java we say many fields and methods)

Symbol is selected in run-time, not inside our code?
mean: when we click on +sign to choose any symbol-say EURUSD--this happen after compilation and at the time of running program.
running program,=attaching it to the chart.

example-3:
if we want to place pending but buy order on USDJPY be careful for the price.
in Buy case price must be equal or lower than current price. (now is 110.33)
also be carful for syntaxs
