Asked & Answered

Hi all,

I thought I had my answers with the following code:

double range[5];

for(int i=1;i<5;i++)

{

range={High-Low};

int Max=ArrayBsearch(range,10,WHOLE_ARRAY,1,MODE_ASCEND);

double MaxRange=(High[Max]-Low[Max])/Point;

}

Print("Max Range: ",MaxRange," found at index: ",Max);

But it still just returns the last index not the largest range index.

Any further help would be appreciated.

Here's the fix:

[code]

double range[5];

for(int i=1;i<5;i++)

{

range={High-Low};

int Max=ArrayMaximum(range);

double MaxRange=(High[Max]-Low[Max])/Point;

}

Print("Max Range: ",MaxRange," found at index: ",Max);

This could be used to get the highest/lowest(using ArrayMinimum(range)) of the array to compare any variables.

Hope this helps,

SaxMan

 

Same Code with additions

Added:

* Minimum range

* Vertical Lines to highlight Max and Min range bars:

double range[2000];

for(int i=1;i<2000;i++)

{

range={High-Low};

int Max=ArrayMaximum(range,WHOLE_ARRAY,1);

int Min=ArrayMinimum(range,WHOLE_ARRAY,1);

double MaxRange=(High[Max]-Low[Max])/Point;

double MinRange=(High[Min]-Low[Min])/Point;

}

Print("Max Range: ",MaxRange," pips found at index: ",Max);

Print("Min Range: ",MinRange," pips found at index: ",Min);

int time1=Time[Max];

int time2=Time[Min];

ObjectCreate("stats1",OBJ_VLINE,0,0,0);

ObjectSet("stats1", OBJPROP_TIME1, time1);

ObjectSet("stats1", OBJPROP_COLOR, Red);

ObjectSet("stats1", OBJPROP_WIDTH, 1);

ObjectCreate("stats2",OBJ_VLINE,0,0,0);

ObjectSet("stats2", OBJPROP_TIME1, time2);

ObjectSet("stats2", OBJPROP_COLOR, Blue);

ObjectSet("stats2", OBJPROP_WIDTH, 1);
 

Code complies, but does not display value

extern Bool Direction_Up=true;

if(Direction_Up==true) Dir="UP"; ///////////This is wrong conversion - How do I convert it to the proper syntax????

ObjectCreate("Dir", OBJ_LABEL, 0, 0, 0);

ObjectSetText("Dir", 10, "Arial", White);///////////This is wrong - How do I get it to display UP on the screen????

ObjectSet("Dir", OBJPROP_CORNER, 1);

ObjectSet("Dir", OBJPROP_XDISTANCE, 36);

ObjectSet("Dir", OBJPROP_YDISTANCE, 120);///

Hi,

int start()

{

int i;

if ((Year() >= X) && (Month() >= Y))

{

Comment("===========",expired,"===========");

return(0);

}

GetPosition = StrToTime(StrGetPosition);

StartOrderTime = StrToTime(StrStartOrderTime);

EndOrderTime = StrToTime(StrEndOrderTime);

return(0);

My Question is :

is GetPosition, StartOrderTime, EndOrderTime will be executed?

Cheers

 

Questions

Hi,

A friend of mine told me about this site. She toled me they have the best mql programmers.

Here's one:

If I set a code, for example....to buy at a 15:30(most of the news time), I checked the economic calendar.

if (Hour()==15)

{

if (Minute()>=30)

{

if (Seconds()>=00)

[/PHP]

After this, something like this goes:

[PHP]

OrderSend(Symbol().......................

Everyone writes it different,hehe.

Why can't it be the same?

Okay, here's the deal. For the above code, I want the OrderSend........and the continuing part to create a BuyStop 30 pips above the price at 15:30:00, and a SellStop 25 pips underneath the price at 15:30:00.

I asked my best friend, and she said to ask you guys. So, I really hope you guys are a big help.

I've spent weeks trying to figure out this code. I'm not kidding. So, will anybody that does coding in mql4 help me?

Hi Iscuba11,

see code for fix & explanation

extern bool Direction_Up=true; //-- bool with a lower case "b"

string Dir; //-- Dir has to be declared as a string

if(Direction_Up==true) Dir="UP";

ObjectCreate("Dir", OBJ_LABEL, 0, 0, 0);

ObjectSetText("Dir",Dir, 10, "Arial", White); // -- you left out the text to print - you named the object only.

ObjectSet("Dir", OBJPROP_CORNER, 1);

ObjectSet("Dir", OBJPROP_XDISTANCE, 36);

ObjectSet("Dir", OBJPROP_YDISTANCE, 120);

Hope this helps,

MQL4: automated forex trading, strategy tester and custom indicators with MetaTrader

search for OrderSend() - docs

Quote

OrderSend - MQL4 Documentation

int OrderSend( string symbol, int cmd, double volume, double price, int slippage, double stoploss, double takeprofit, string comment=NULL, int magic=0, datetime expiration=0, color arrow_color=CLR_NONE)

symbol - Symbol for trading.

cmd - Operation type. It can be any of the Trade operation enumeration.

volume - Number of lots.

price - Preferred price of the trade.

slippage - Maximum price slippage for buy or sell orders.

stoploss - Stop loss level.

takeprofit - Take profit level.

comment - Order comment text. Last part of the comment may be changed by server.

magic - Order magic number. May be used as user defined identifier.

expiration - Order expiration time (for pending orders only).

arrow_color - Color of the opening arrow on the chart. If parameter is missing or has CLR_NONE value opening arrow is not drawn on the chart.

So in our case we have this:

OrderSend(Symbol(),OP_BUYSTOP,0.1,Ask+30*Point,3,0,0,NULL,1,0); OrderSend(Symbol(),OP_SELLSTOP,0.1,Bid-25*Point,3,0,0,NULL,1,0);

That is it!

No stoploss, no takeprofit.

Please note: your broker (most likely) will not accept new orders on 15:30, don't even dream about it. Yes, it will work on demo but not on real account - not any time sooner than 5 minutes before the news and no less than 3 minutes after the news.

Use search engines

Google

Yahoo!

and others.

PS:

if you want me to write an EA for you, PM me.

 

You made my day and weekend with the code correction. Thanks ever so much!

May you have a blessed weekend!

Sincerely,

Dave

How can use ObjectCreate on an indicator-separate-window versus the chart-window???? This would be handy!
