Hi friends and enemies

Here is another free Expert Adviser to this community.This Expert Adviser belongs to me and I paid money for it .It may require further development and coding and testing .Please feel to contribute in updating this EA and stating on the EA the improvements coded .Please feel free to write down the set of rules as to how to use this E A.

It is useful and can be used with a poorly written EA as slave and master.

The purpose of the EA is to override all the stops and take profits etc .It is not tested yet and I will let all the testers contribute with their testing.Please post if the E A is functioning properly and what else needs to be coded and any missing codes.

If more than one EA is used ,say for example 5 .it will override the instructions on all.

Post my mistakes and I will correct them.

I have attached the modified ea and master. You need to place the
master on one chart first and then the slave on another chart. The magic
number does not matter. If there are any problems with it please let me
know.

To make a slave and master you need to do the following.

Create a master ea that creates and maintains global variables using
commands like the following :GlobalVariableSet("TradingAllowed",false);
please note.....global variables only save as numbers so false shows as
0 and true as 1

You then get the slave to check the values of the global variables
before making a trade....eg.
if(GlobalVariableGet("TradingAllowed")==1)opentrad e();
or if(TotalSellOrders()< GlobalVariableGet("Max_Shorts")) SellOrdOpen();

You should be able to adapt all your ea's to this master as I have not
made the master exclusively look for this slave;

Below is an explanation of some of the new variables I have used.

On the slave there is the option OrderSet, this is so you can select
which sl and tp strategy the ea trades.

On the master if a value is set to 0 this function will not be used.

extern int TradeHours =24;
extern int MaxAllowedTrades=5;
If more than 5 orders are opened within 24 hours the ea will disable trades

extern int DailyAccountLossAllowed=5;
If the account looses more than 5% in 24hours it will dissable trading;

extern int DeletePendingAfter =1; if any pending order is open for more
than 1 hour it is deleted

extern int CloseOrdersOnFridayAt=16; the hour on friday that all open
orders will be closed

extern int WeekendDissable=16; the hour on friday that new orders will
be dissalowed at
extern int WeekendEnable=10; the hour on monday that new orders will be
allowed again at
extern int NewsDissable=16;
extern int NewsEnable=10;

Hi

There were many other functions I expected to be included in this EA .There is room for improvement and additional coding

ea saves and maintains a file on the

>> I will code the slave to consult this file before making any trade.

>>> 1)The master will be created with maximum emphasis on safety and

>>> before resending it will check orders filled and open positions , it

>>> will do the same everytime the metatrader programme reboots and will

>>> never allow orders above the maximum to be sent.

>>>

>>> 2)Sometimes, when several EAs start trading at the same time, trading

>>> functions may fail because the trading context is busy and only one EA

>>> this, you can either use WaitUntilTradingIsAllowed() function or

>>> StartTrading()/StopTrading() functions.We only had one EA.Please take

I noticed a problem immediately with this EA.

The "Close All" function shouldn't work properly as coded.

Reason being: MT4 will only execute one operation per tick.....

void CloseAll()
{
int total = OrdersTotal();
for(int i=total-1;i>=0;i--)
{
OrderSelect(i, SELECT_BY_POS);

It should be more like "while(OrdersTotal()>0)" etc......

That will force the program to loop instead of moving on after one order closes.

I could be wrong, but that is based on first glance.

__________________
Ideas are not trade advice.

There are no OrderSend() functions in the code! It will not open any trades because of this!

__________________
Ideas are not trade advice.

It will open trades from the slave and manage from the master.

The early bird EA is attached .This is where he modied something .At the top
extern int OrderSet =1;


Sorry I did not post earlier because I was afraid of copyright infringement

You are a coder and it would help if you could make the changes and post the EA .I am not a coder but the previous coder did all the work.

I am happy to leave this in your capable hands to handle this EA

Thanks

Hi folks

I want to take this further and put in 10 slaves on one master.Is it possible?

.



To start with I will provide one profitable EA , programmer will make one master EA and put 6 copies of the EA as slaves.The six EAS will work at the same time from one chart..Each EA slave will have different settings for mas,triggers etc.Each slave will have its own stop loss ,take profit and separate entry signal.



When the main working master is delivered ,I will provide 3 further EAS or logic to be input for each of the 4 additional slaves.



The master will control all the slaves and disable each individual slave if maximum orders long or short orders are generated.If maximum 4 long/short orders are open , any further signals for more longs will be disabled



Slaves will be set with override code, which if inserted will use take profit ,stop losses and type of trailing stop, only from the slave and each slave will have its own override key to override master.



The EA will read the market prices and go through the following steps

1)read market prices and activity of prices

2)slaves generate order signals

3)slaves pass order to master

4) master reads success probability count level of between 1 to 10

5)master reads stop target count level of between 1 to 10

6)master checks filters

7)0If stop loss probability and success probability above x ,master places order

8)If long and short positions are open at same time ,master widens stops according to total potential gain /probabilities

9)If part positions closed at a profit master reassess the positions and reverts to old stop loss levels



This is not an easy 2 page EA .It is an ugly nightmare to debug and compile.It is a big job



How long will it take to compile the first stage of 6 slaves into one ,plus master set up with probability counts for entry and stops?



I would want a fully working EA and MQL files fully debugged ,before I go to stage two and 4 additional masters




Regards

If you are talking about copy trades tool so I am testing it right now. Did not post yet as it is still in testing:
- TradeSpy_v2.1 indicator to copy trades to the other Metatrader's folder in real time (copy slaves' trades);
- SpyTrader_v1 EA (master EA)

It was created by Igorad according to many requests (including ElectricSavant request in elite section).

New Digital

What I am trying to achieve is to use 10 to 12 slaves EAS.These EAS are standard EAS but are used as a slave.The 10 to 12 EAS in a porfolio are managed by one master EA.

You could have 10 trades opened from a portfolio on Eur/usd and some at the same price and similiar stops.The master would limit the 10 EAS to only 4 open orders

10 EAS generate signals but the master picks the best 4 TRADES based on probability counts , and sends to broker

OILFXPRO

As to copy trades from 1 or several Metatraders to one or several other Metatraders with some settings (slaves lot size and MM; or our lot size and MM, any broker, maximum trades options and so on) so i am testing it right now. I will post it of course but need to speak with Igorad first.

As to portfolio manager
(manage some EAs concerning openning orders, equity, to stop trading, to start trading, interrupt during the trades - one EA is trading but the other is waiting - how many seconds with 'agreement " to metatrader software, switching slaves on or off according to the market condition predicted; and so on)
so it is difficult task.

You did some good posts about it in this thread.

There are some library files which are helping to do it (controlling the trades in case of many trades opened) - in Metaquotes base.
So, it can be fine if coded as library file or dll ... because according my understanding it should be very big code ...
But may be ... just to start with small ...

Anyway it is very good idea.
