New comment
 

hello,

im new to mql language and also almost new to programming.

i was found some source of line cross alert.

and i was add keyboard event to source to close my order.

so it should have to working when current candle crossed(Close[0]),it should have to be close order but this time

it just closed order when price line touch Alert line.

You can use ObjectGetValueByShift() to get the value of the trend line for bar 1, you can then check the OHLC values of the bar to see if it is fully below the trend line.
 

hello admin!

if you don't mind would you some show me sample code or source?

So you want someone else to write this code for you ?

Go here: Write mt mlq4 code for me

 
Listen, buddy, do you know that this site has a search capability? Do you also know that this site has a section called Codebase with many indicators sitting there waiting for you to download and start learning the language. Just do a search "trendline alert" and you will find so much interesting stuff for you to start working with. Or do you think it is easier to ask a question and beg for an answer. Ok this problem maybe solved, how about the next, and the next, and the one after that?
