How do you know about a market in MT5? - MQL4 and MetaTrader 4

Sergey Diubakin 2011.11.09 10:47 #3271

If there is no set of parameters from ФВ > 30, then the Expert Advisor is wasted.

How many EAs do you have with this PV and at the same time the number of trades is at least 200 (100 on Buy and 100 on Sell)?

If you set not only "net profit" parameter, but also "recovery factor" or the maximal drawdown - and look from these positions.

In MT5 such a thing is already available, very convenient and clear, but one cannot make "cuts" like in this program. Maybe you should ask the developers and they will do it...

FelixFX:

Hello!

I can't figure out how to make a custom function return multiple values? Could you give me a hint?

This is not Pascal - there are no procedures...:-) One function - one value...:-)

See the GetMarketInfo function of the script for closing all orders - using arrays is possible.

...

That's enough. FS = 34. And in fact, that's not the question you asked me...:-) Especially, if you read these branches - the author has clearly written there that these figures

30 for TC and 100 for the portfolio - his IMHO.... "Don't mince words, please. I didn't claim that's the way it should be. 30 is my personal whim. No more than that... "

Sorry, didn't notice you were quoting someone else, but the report is impressive.

please help!

The code opens two pending orders and should modify both...

But it only modifies the salt pending.

q=20;

pb=Ask+20*Point;

ps=Bid+20*Point;

Tb=Ask+50*Point;

Ts=Bid+50*Pointl;

look at the numbers to see what you get

if (OrderType()==OP_BUYSTOP)
{
 t=OrderModify(OrderTicket(),pb,0,TPb,0,CLR_NONE);
 if (!t) Print("BUY О Ш И Б К А = ",GetLastError());
}
                                    
if (OrderType()==OP_SELLSTOP)
{
  t=OrderModify(OrderTicket(),ps,0,TPs,0,CLR_NONE);
 if (!t) Print("SELL О Ш Ы Б К А = ",GetLastError());
 }

you want to place both a buystop and a sellstop 20 points above the current price

ilunga:

see what you got with the numbers.

you want both buystop and sellstop to be 20 points above the current price

I typed it in by hand...

In the code it goes like this:

pb=Ask+20*Point;

ps=Bid-20*Point;

Tb=Ask+50*Point;

Ts=Bid+50*Point;

more tips, please.
I can't get the vertical shift up and shift2 down indentation from the wrist.
this parameter should be set differently for each chart.
I get a compile-time error

Tb and Ts in the sense of TPb and TPs? then again, went the same way, but the orders are different

take out all the values and see what you get
