Keep in mind you may need to continuously store the spread as well ... depending on type of EA you are writing. otherwise useless

 

it is HIGH [0] -- current bar that just START

for low , I don't know , maybe low[1]

 

Right order to put OrderSend(),OrderModify()

Day ago i read topic in forum about function OrderSend() and OrderModify()

and this topic give me a clue why some EA work and other did not, and i wonder how to check if function OrderSend() and OrderModify() is properly written.Any examples?

 

hi all...

Please tell me how to code for obtain the list of all pairs in MT4?

thanks

Charles

Hi,

I no it is not right to write Ask[1] but how can I get the Ask-Price from the last tick??

Thank you!

You have to save the ticks in real time, and then access them from your EA or indicator. I could try to code an example for you if you are still interested.

Take your time man,, i believe it is easier to do in Mql5 so just wait for things to get settled

 

getting magic trend values in a variable...

hi!!

im working on a EA and im wondering how i can get magic trend indicator values in a variable. obviously theres no native function for magic trend, like iMA does for moving averages and so....

so far it looks i have to code it from scratch. but i dont find any info about the math!

could someone help?

Look for information how to use ICustom function in MQL4 . With this function you can call external indicators in your EA
