Learning to code...

Hello everyone,

I decided to start learning how to code things on my own.

I'm working on my first EA but I don't know how to draw things on the chart.

lets say I had a Variable called BuySignal which was a price and I wanted to draw a horizontal line on the chart at that price and make a text object stating that price; what would be the code for this?

I tried following the MQL4 site but i'm not quite understading it I guess.

Thanks for the help

this kind of question is what i live for

lets go deep into objects

objects is what youl be creating

first read my tutorial

after going through my tutorial, if you still need help
just ask

my tutorial was created just for people like you

i cover objects in a very detailed way

Thanks Trend,

I'll have a look at it over the weekend... i'm trying a bunch of diffent things in the EA just to learn all the aspects of coding in MT4... I'll be asking questions frequently.

Thanks again looks great!!

TrendChaser or anyone interested in helping,

I am attaching a EA i'm trying to code. its a simple box breakout strategy which measures a high and low based on a time range and will buy the high, sell the low at market.

the problem i'm having is that once a signal is hit it just opens 100's of trades instead of just one and eventually freezes up the back test.

can anyone look at the code and explain to me what i'm missing, what i'm doing wrong... I made notes in the EA so that you understand my logic but keep in mind I could be way off as this is the first one I have ever tried.

i'm doing this as a learning experience so please don't simply post another EA that does the same thing, I need to know what i'm doing wrong.

you used these brackets in a strange way to me
{

right here

while (lastTrade!= DayOfWeek()){
while (curHour < EndHour + Expire){

maybe you shouldnt use the while, your not in a loop or anything
i would just put those 2 rules here


then test and find the other flaws

another thing i noticed, is your using return operators everywhere, i dont use them, i think there for use in functions, your not using functions, i may be wrong

only time i ever use return operator, is in these type of functions

int example()
{
return(something);
}

double example()
{
return(something);
}

bool example()
{
return(something);
}

i do not use them in void type functions, i only use them if i need to return some value

also, this is likely the reason your getting alot of trades

if(ticket<0)

try this
if(ticket>0)

Thanks again Trend; your the man,

I'm going thru it now i'll post back in a few.

Hey Trend,

I Changed what you suggested but im still getting the multiple orders... is there another way you can think of in order to limit trading to once a day... Thanks buddy

heres how i do it


that trades once a bar, you can set the ibarshift to daily tf

i recommend using global variable to be reliable

heres the version of the code above using globals
