Hanover replies to PMs

Based on Erebus' idea, attached below is a ATR based trailing SL indicator that I used a few years ago. Also a ZIP of all of the ATR indicators that I was able to find in my archive. There are others here here and here, all found easily using Google.

Hi hanover
i want to find way how to measure angle degree .
and found someone who already made such like real angle measurement EA.
would you know how to measure real angle ?
here thread Hayseed made such like EA.

pls check and if you know how to pls share .
thanks you ^^

Good programmers get used by mostly people with flawed ideas. True or False?

You can calc the value of an angle of a right-angled triangle using trigonometry.
In my screenshot below, the tangent of angle C = length of line AB divided by length of line BC.

Therefore given the size of either the angle and one side, you can calc the length of the other side; or given the length of both sides, you can calc the angle.
All of this is high school math.

This is possible because both AB and BC are measured using the same units, e.g. cm. The problem with price charts is that the y-axis is price, while the x-axis is measured in a different unit, time. Hence, unless you arbitrarily define one hour (or day, or whatever) to represent a certain number of pips, you're no longer comparing apples with apples, and the trig rules become meaningless. (That's one reason why I've never bothered to study the works of WD Gann).

Another problem is that the angles change whenever you change timeframe, or the chart scale, or zoom in/out, i.e. they are dependent on the frame of reference.

There is a menu option 'Trendline by Angle' in MT4, but I'm not sure how this maps time into price (or vice versa).

I watched the first 3 mins or so of your video, but I don't understand what the presenter is getting at. If the presenter is the same 'hayseed' who posts here on FF, then you could ask him. Apart from being a knowledgeable trader/programmer, he is also a very friendly and helpful gent.

thanks for your great detail explain!
i already sent msg to hayseed and hope to see his reply!
thanks again ^^

Given that the vast majority of wannabe traders lose (whether it's 80%, 90%, 95%, 99%, whatever -- it's still a significant majority), then it's fairly safe to assume that any unproven idea will be unprofitable, if run for long enough; and regardless of the proficiency of the programmer. At least that has been the case, in my experience: explained in more detail here and here.

MetaEditor/compiler for build 509

MetaQuotes changed their MQL4 programming language in the move from build 509 to build 600. As a result, many old indicators and EAs compile with errors in the latest MT4 builds. To make these work, you will need to either:
(a) persuade a programmer to recode them for you, OR
(b) you can compile them yourself using MetaEditor/compiler build 509. To run this, all you need to do is:

1. Go to MT4, and choose menu option: File.....Open Data Folder

2. Unzip the contents of the attached ZIP file into that folder. This should load all of the required files into the correct folders.
3. Download your required indicator (MQ4 file) into the ..../MQL4/Indicators folder, or your required EA (MQ4 file) into the ..../MQL4/Experts folder.

4. Go back to folder ..../MQL4 and double click on metaeditor.exe (this runs the MetaEditor/compiler build 509).
5. Load the required indicator or EA (menu option: File....Open....) into MetaEditor, and then press F5 to compile it.
6. Assuming you get 0 errors, return to MT4, open the Navigator (press Ctrl-N), right click and choose 'Refresh'.

The indicator or EA should now be sitting in the relevant tree ('Indicators' or 'Expert Advisors') ready to be attached/dragged onto your MT4 charts.

Repeat steps 3, 5 and 6 to compile any additional indicators or EAs.

Hello Hanover,
First of all, i would like to thank Hanover for such good contribute to forexfactory, i have learn much since my pass recent years of trading and i did improve myself much.

Hanover..
I came across your post : https://www.forexfactory.com/showthread.php?t=173870

this indicator plot all the "15" value on screen

How can i get "15" each value and store in double variable?
example :
Double Box_Edge_1 = %$;
Double Box_Edge_2 = %$;
Double Initial_stop = %$;

Hope you can guide me for the Code. I need to get all the "15" value and store in each variable so i can use the value.

Thanks in advance.

Sorry, but I don't understand what you're trying to achieve.

To set values in a variable:
string variable_name_char = "15";
int variable_name_integer = 15;
double variable_name_float = 15.0;

To set values in the Fibo descriptions, just type whatever text you require, e.g.:

Hello Hanover,
I downloaded your BoxFibo indicator from https://www.forexfactory.com/showthread.php?t=173870, this indicator will plot the value on the chart. see below...



As we see in this chart above, there is 15 value which plotted on screen, the code for plotting the value on the chart is as below....

ObjectSetFiboDescription(objname,0,"Box Edge = %$");
ObjectSetFiboDescription(objname,1,"Initial Stop = %$");
ObjectSetFiboDescription(objname,2,"Box Edge = %$");
ObjectSetFiboDescription(objname,3,"Entry = %$");
ObjectSetFiboDescription(objname,4,"TP2 Stop = %$");
ObjectSetFiboDescription(objname,5,"TP1/3 Stop = %$");
ObjectSetFiboDescription(objname,6,"TP2 = %$");
ObjectSetFiboDescription(objname,7,"Entry = %$");
ObjectSetFiboDescription(objname,8,"TP2 Stop = %$");
ObjectSetFiboDescription(objname,9,"TP1/3 Stop = %$");
ObjectSetFiboDescription(objname,10,"TP2 = %$");
ObjectSetFiboDescription(objname,11,"TP3 = %$");
ObjectSetFiboDescription(objname,12,"TP3 = %$");
ObjectSetFiboDescription(objname,13,"TP4 = %$");
ObjectSetFiboDescription(objname,14,"TP4 = %$");


Question: how can i get those 15 value and store in a double variable? i am asking from the aspect of programming mql4.

Example :

Double value_1 = ObjectSetFiboDescription(objname,0,"Box Edge = %$");
Double value_2 = ObjectSetFiboDescription(objname,1,"Initial Stop = %$");
Double value_3 = ObjectSetFiboDescription(objname,2,"Box Edge = %$");
Double value_4 = ObjectSetFiboDescription(objname,3,"Entry = %$");
Double value_5 = ObjectSetFiboDescription(objname,4,"TP2 Stop = %$");
Double value_6 = ObjectSetFiboDescription(objname,5,"TP1/3 Stop = %$");
Double value_7 = ObjectSetFiboDescription(objname,6,"TP2 = %$");
Double value_8 = ObjectSetFiboDescription(objname,7,"Entry = %$");
Double value_9 = ObjectSetFiboDescription(objname,8,"TP2 Stop = %$");
Double value_10 = ObjectSetFiboDescription(objname,9,"TP1/3 Stop = %$");
Double value_11 = ObjectSetFiboDescription(objname,10,"TP2 = %$");
Double value_12 = ObjectSetFiboDescription(objname,11,"TP3 = %$");
Double value_13 = ObjectSetFiboDescription(objname,12,"TP3 = %$");
Double value_14 = ObjectSetFiboDescription(objname,13,"TP4 = %$");
Double value_15 = ObjectSetFiboDescription(objname,14,"TP4 = %$");

"I need to get those value and store in the Double Variable in Order to use in calculation. "

Hope you understand what i mention, please advise me on how to get the value into the double variable.

Thank you very much.
Regards

I use MQL4 build 509, and my reply below reflects that. There may be better solution using build 600+, but you'll need to ask another programmer.

Sadly, the MQL4 function
string value = ObjectGetFiboDescription(objname,0);
will return a value of: Box Edge = %$
instead of: Box Edge = 1.2995
If it did the latter, you could use this function, and then simply extract the numeric value into a 'double' variable.
But it doesn't work that way.

The only way I can think of getting the values is by calculation, e.g. if high_price and low_price are the 100 and 0 price levels across which the fibo object is stretched over, then the price at (for example) fibo ratio 38.2 is equal to:
double value_1 = low_price + (high_price - low_price) * 38.2 / 100;

Thus your code could look something like:
Hope I understood you correctly this time.

Hello Hanover,
Really appreciated the kind advise on the mql4 code, and the code seem populate the value as i wanted. But, how abouyt the decimal value, how to match each currency decimal value as the price on the market by each instruments ?

The value on plotted chart as below....


The code which i insert as code by you, it printf as below....


from both value, seems that the only problem is on the decimal value. How to solve it?

attachment on the new modified BoxFibo.mql4 as below



Regards

Sorry, I don't understand what you mean by this.

If you want to match the value to the relevant fibo description:

value_00 is "Box Edge"
value_01 is "Initial Stop"
value_02 is "Box Edge"
value_03 is "Entry"
value_04 is "TP2 Stop"
value_05 is "TP1/3 Stop"
value_06 is "TP2"
value_07 is "Entry"
value_08 is "TP2 Stop"
value_09 is "TP1/3 Stop"
value_10 is "TP2"
value_11 is "TP3"
value_12 is "TP3"
value_13 is "TP4"
value_14 is "TP4"

The values depend not on the market price for an instrument, but on how you plot the fibo object.

Hello Hanover,

after i get those value.... i tried to "printf" allthe value which store in the variable as below

printf(value_00);
printf(value_01);
printf(value_02);
printf(value_03);
printf(value_04);
printf(value_05);
printf(value_06);
printf(value_07);
printf(value_08);
printf(value_09);
printf(value_10);
printf(value_11);
printf(value_12);
printf(value_13);
printf(value_14);

Result is :

As my broker on GBPUSD is on 4 decimal value, suppose the value is 1.3010 instead of 1.301

how to get the exact price value shown on the plotted chart?

regards

Mathematically, 1.301 = 1.3010
(it also equals 1.30100000000000000000000000000000000000.....)

You can use NormalizeDouble() to adjust/round a price to a set number of decimal places. I can't guarantee that it will produce the exact number shown on the fibo plot, because I have no control over how MT4 operates. It is the best solution that I can suggest. It's also possible that the value is being truncated to 1.301 by the printf() function.

So, assuming you want all of the values rounded to 4 decimals, you could try adding code like this:
value_00 = NormalizeDouble(value_00,4);
value_01 = NormalizeDouble(value_01,4);
etc

Other functions you could try include:
value_00 = MathRound(value_00*10000)/10000;
or
value_00 = MathFloor(value_00*10000+0.5)/10000;

or you could try converting the value to a string, and then back to a double:
value_00 = StrToDouble(DoubleToStr(value_00,4));

I haven't tested these, you'll need to try them for yourself. Use the links to get more info.
You've now exhausted my knowledge on this topic, I don't know any other way to try to help you.

[NOTE: If you want help on any MQL4 function, Google: [functionname] mql4
The online MQL4 user manual should pop up within the first few links returned by Google.]

Thank you hanover... really you are the best. god bless you always.

Hi Hannover!

I've got a Doji Bar Indicator with inbuilt Popup alert function (attached herewith) and I'm just wondering if you could help me get a PUSH alert functionality added to it or if you know of any - already existing - indy that does the same?

Thanks for your kind attention.

Regards

Ben

I do all my coding in MQL4 build 509. If your indicator is written in build 600+, I can not help you. What I suggest is that you post your request in one of the "I code for free" threads, hopefully another programmer will help. Also, you'll need to provide the mq4 file, the ex4 file is unreadable.

In build 509, there is a SendMail() command, which can send text to an e-mail address. Then depending on your telecoms provider, e-mails could be routed to your mobile device. But you first needed to press Ctrl-O and set up the options in the Email tab/panel correctly.

In build 600+, I see that there is also a SendNotification() command, which looks like it sends a Push Notification. But again, you need to press Ctrl-O and set up the options in the Notifications tab/panel correctly (see screenshot). This probably differs depending on your smartphone (Android, iPhone, etc); I don't know how to do this. However, there's some good info by FerruFX here (see the Word doc attached to post #17). In terms of modifying the program code, it's probably just a case of adding a
SendNotification("text to send");
command at the same time it does the pop-up alert. But nobody can do anything without the mq4 file.

Thank you for your prompt feedback, I appreciate.
Unfortunately I don't have the source file for the Doji-Indicator above.

A brief insight: how to combine TA and FA into a viable trading system

I use S/R (or S/D if you like) levels and BV on the M15 to allow me to judge the likelihood of whether given technical levels will hold or not. S/R says that they will, unless FA trumps this. The GU chart below illustrates the type of thinking that I use.

Candle (A) is extremely high volume off Wed's FOMC minutes. The latter is very important, hence I expect this to hold as a strong tech level, confirmed by the high vol. This is also further supported by two levels immediately below, including 1.2400.

The orange zone was created by the GBP bond auction (B) and later by USD ISM (C). These are less important, esp as the outcomes were largely unsurprising, although the vol on the latter is quite high. We then get wide resistance at ~1.2975. This narrow consolidation range (white lines) would have allowed a breakout trade either way (if one uses this type of strategy). Or anticipate the bounce (that in hindsight occurred) after price bounced back into the succession of lows created during the Asian session. A nice (potentially) high RR sell (D).

GBP manufacturing comes out way lower than expected (-0.2% v +0.5%) (E). This surprise was big enough to cause the weaker orange zone support to give way, but note how the stronger green zone (FOMC minutes) has held thus far. However, price is struggling to break above the two dark blue resistance lines, and possibly flipover resistance created by the low at (C). All of this is not unexpected, as I expect the market to remain slow/flat price for the next 3 hours, as institutional traders await NFP (F).

With this type of intraday trading, the question I'm frequently is whether news has the impetus to break the S/R levels, whose strength I attempt to assess from prior volume, visibility, and the importance/deviation of news expectation that created them. Also I use the room up/down indicator as OB/OS to decide how much further price is likely to move within the current day, and again whether the news outcomes have the impetus to drive it beyond these.

TA and KISS proponents will probably say that this is too complex. The anti-volume lobby will say that this is merely br0ker-specific tick volume. All these folk are correct. But whatever analysis gives the best insight as to what's most likely to happen is king in my book, and this is the best that I've found so far. Each to their own.

[EDIT] Wow, got that badly wrong! GBP is tanking. Since I quit my membership with Jarratt Davis I don't have a news feed. Perhaps there is other UK based news causing this fall? ......... Here is Boris Schlossberg's analysis. FA strong enough to trump S/R in this instance.
