Hi hanover, do you, or one of your followers have an indicator to draw S/R and trendlines into a subwindow to give alarms when one of the lines is touched or broken? For example: RSI 21 breaks a horizontal level, or breaks a trendline and you got a message popup. Could you help please? That would be great. Regards

{quote} I don't know any indicator that alerts on a break of a subwindow trendline. But if you're looking for an indy that alerts when RSI crosses in/out of predetermined zones, then FerruFX's RSI indicator here might help you.

{quote} well, hanover.... I guess when even a experianced coder/trader like you doesn t know about a way to get an alarm when a trendline or a support/resistance line in a any subwindow indicator (not only rsi with predermined zones) it is time to create a way. What you think... would this be a challenge for you...? ( I know it is not easy to code such a tool)

{quote} I dont belive Hanover said he doesn't know how to do it. It doesn't sound hard to do. He kindly took the time to find a possible solution for you and at no point was he soliciting his skills to you. Did it seem like it was an idea that sparked his interest? Try here, there are lots of willing coders offering their services for mql4 and mql5. https://www.mql5.com/en/job Hope that helps.

{quote} Sorry if I misunderstood, but in your original post it seemed like you were asking if there was already an existing indicator. Assuming a new indicator is being created: if the trendline always ends at the right hand edge of the chart, then its y-value can simply be compared to the indicator's current value, to see if the line has been crossed. Otherwise the programmer would need to use straight-line math to obtain the equation of the trendline; after the equation has been established,...

{quote} Hi David and all! Long time. Actually, there's an MT4 command for this. ObjectGetValueByShift("Line Name",shift) will return the y-value (price) for the line at the candle specified by the shift. Edit: I don't know if it works in a subwindow, I'd bet it does.

{quote} Are you going to give it a college try? I keep looking at it the last few days on and off, and I'm just kind of put-off by some of the things I am led to understand about it. It sounds like a great language if it jives with your way of thinking, but I think I'm far too content with sticking with PHP. I particularly dislike the way I see classes and objects being done in Python. Feels a bit "javascript" to me, and that's not a good thing by any measure.

{quote} Sadly my knowledge/experience of object-oriented coding is not great. There was a university graduate running free Python night classes at the local computer club last year, but unfortunately I got ill and was unable to attend. Anyway, lately I've actually been focused on (gasp!) trading, and am giving programming a rest for a while.
