Hello, for some reason I can't figure out how to convert the Time[] seconds number (126858000) to display the actual 24hr (Hour+Minute) time.

What is the formula please?

Thanks

You could need to use datetime() function and make and array.

Check the code on the Clock v1_2 auto (I altered the original to show seconds besides the hour and minutes in the "bar" count.) It will get you some ideas. You need to allow dlls.

How to change MA 5 decimal to 4 decimal?

Hi,

I'm using FX Pro, (uses 5 decimal and 3 decimal for jpy) how do i edit the code for MA(moving average) to show 4 decimal for non jpy pairs and 2 decimal for jpy pairs on data window for metatrader 4? Or is there any other MA indicators that can do that?

Thank you

Help with text lines

Hi

I've managed to create an indicator (my first) based on other indicator found in other forum, I have a little problem, the indicator has 8 lines I want them labeled but only get one of them with label, can somebody figure out what the problem is?

this is the labels code:

ObjectCreate("1", OBJ_TEXT, 0, 0,0);

ObjectSetText("1", " 1",fontsize,"Arial",Red);

ObjectCreate("0,75", OBJ_TEXT, 0, 0, 0);

ObjectSetText("0,75", " 0,75",fontsize,"Arial",Red);

ObjectCreate("0,55", OBJ_TEXT, 0, 0, 0);

ObjectSetText("0,55", " 0,55",fontsize,"Arial",Red);

ObjectCreate("0,35", OBJ_TEXT, 0, 0, 0);

ObjectSetText("0,35", " 0,35",fontsize,"Arial",Red);

ObjectCreate("-0,35", OBJ_TEXT, 0, 0, 0);

ObjectSetText("-0,35", " -0,35",fontsize,"Arial",Red);

ObjectCreate("-0,55", OBJ_TEXT, 0, 0, 0);

ObjectSetText("-0,55", " -0,55",fontsize,"Arial",Red);

ObjectCreate("-0,75", OBJ_TEXT, 0, 0, 0);

ObjectSetText("-0,75", " -0,75",fontsize,"Arial",Red);

ObjectCreate("-1", OBJ_TEXT, 0, 0, 0);

ObjectSetText("-1", " -1",fontsize,"Arial",Red);

if (PBuffer1!=PBuffer1) ObjectMove("1", 0, Time,P);

if (PBuffer2!=PBuffer2) ObjectMove("0.75", 0, Time,Q);

if (PBuffer3!=PBuffer3) ObjectMove("0.55", 0, Time,R);

if (PBuffer4!=PBuffer4) ObjectMove("0.35", 0, Time,S);

if (PBuffer5!=PBuffer5) ObjectMove("-0.35", 0, Time,T);

if (PBuffer6!=PBuffer6) ObjectMove("-0.55", 0, Time,U);

if (PBuffer7!=PBuffer7) ObjectMove("-0.75", 0, Time,V);

if (PBuffer8!=PBuffer8) ObjectMove("-1", 0, Time,W);

P,Q,R,S,T,U,V,W are declared with the indicator calculation

All missing labels are declared in object list but pressing "show" the chart goes nowhere, and editing the object I find out that instead having the rigth date, time and price, they have no price "0" no time "0" and date is 1970/01/01.

Any suggestion for correct this or replace it with something that works is wellcome

 

Fibonacci as an EA filter?

I am trying to implement a Fibonacci filter to my EA in order to maximize the profits and reduce the draw-downs (you know, the good stuff).

I created a Fib function based on Donchian channels and tried it out on my optimizations (WITHOUT RE-optimizing). I was surprised by the lack of consistent improvement throughout my various optimizations.

/*lprice and hprice are the high and low of a large-period (ex. 10080)

Donchian channel.

Various Fib levels are stored in the array L.

*/

L[0] = lprice;

L[1] = ((hprice-lprice)*0.236068)+lprice;

L[2] = ((hprice-lprice)*0.381966)+lprice;

L[3] = ((hprice-lprice)*0.5)+lprice;

L[4] = ((hprice-lprice)*0.61803399)+lprice;

L[5] = hprice;

for (int i = 0; i<14; i++)

{

if (Close[0] L) buys = false;

if (Close[0] > L && Close[0] - FibMargin*pt < L) sells = false;

}

[/CODE]

I also tried

[CODE]

if (Close[1]>L && Close[0]<L) buys = false;

if (Close[1]L) sells = false;

I can plainly see by looking at price action on fib levels that the price obeys the levels as S&R....so why can't I achieve consistently positive results?

Any ideas? Anyone use Fib in a way different to the ways I mentioned?

 

How must I modify this EA, I want no SL if a new order open. The trailingstop is ok.

I hope someone can help me.

Simpliest way, just give very big value on SL input let say 10,000.

 
codersguru:
g_bar1Range = MathAbs( High[ 1 ] - Low[ 1 ] );[/PHP]

This line calculates the range between the High and Low of the previous bar (bar 1).

g_bar2Range = MathAbs( High[ 2 ] - Low[ 2 ] );

This line calculates the range between the High and Low of the previous previous bar (bar 2).

[PHP]g_bar1Body = MathAbs( Open[ 1 ] - Close[ 1 ] );
This line calculates the Body length of the previous bar (bar 1).

Codersguru, I think for g_bar1Range and g_bar2Range no need MathAbs since the return value will never negative (-) value, High will always >= tha Low.
