Clean hi/low indicator

Hello all:

I am looking for a high and low indicator that puts a horizontal line on my chart. So if I happen to plot 231 1-hour candles, I want the indicator to put a line at the highest high and the lowest low. It also needs to display the price label.

Optionally, it would be terrific if the periods could be specified, as in: this is my 1 hour chart that I am plotting, and I want to know the highest high and lowest low of the last X periods, where X in the example above would be 231.

Why do I need this?
I currently do this by hovering the cursor over the presumed highest high and reading off the value at the bottom of the screen, which I then put into an Excel sheet for my trading system. I then do it for the lowest low and move on to the next chart, repeating this every 24 hours.

I have already looked at all the following indicators on ForexFactory here and unfortunately they over-complicate or don't meet this need:
###Daily-Weekly-Monthly Hi-Low; Support and Resistance (Barry); Yesterday High & Low v2.0; Super Signal v3d; i-Sessions; ShadowCandles_V2; Range_v2; #MTF_Support and Resistance (Barry); Trading Session vLines; SDX-ZoneBreakout2; Daily LinesBoxes; KiS_max_min_Avg_Monday Fixed; Pivots (SDX-TzPivots) 3; Pivots (SDX-TzPivots) 9 SR; Auto-Pivot Plotter (Mid-Levels) V1-41

Attached is a picture of what this indicator would look like.

Kind thanks!

RM77,

Try the attached. If you leave NumberOfBars as a negative number, the indy will simply plot highest and lowest price across all of the bars that are currently visible. Otherwise, it will plot the highest and lowest prices across the last N bars that you specify.

This is great, exactly what I was looking for. Many thanks, David!

PS: I just looked at the code of this indicator, hoping to learn a bit from what you have done here, but it's some 20+ pages long. In a pinch, I can collate together some visual basic and write SQL queries, but I guess for now the MetaTrader language will continue to elude my grasp. Would be nice if someone ever wrote a GUI for putting together custom indicators, (a Crystal Reports for MetaTrader language of sorts), I know I wouldn't mind paying for something like that...

Thanks again!

RM77,

Probably 98% of the "20+ pages" of code could be removed. To get jobs done quickly, I simply work from a template, that includes all of the user-defined functions that I've created to 'extend' the MQL4 language (the lengthy "FUNCTIONS LIBRARY" section). I don't bother removing them because (1) I might need them if asked to modify an indy at some future point, and (2) the MQL4 compiler discards any unused functions, so that the executable code remains efficient, in any case.

Your request was (programmatically) very simple, and took me about 10 minutes to code and test. The part that calculates and plots the lines takes less than 10 lines in the plot_obj() function.

I notice that you mention Crystal Reports. Have you used Clarion? I am a long time Clarion programmer, although I haven't upgraded my version since c. 1997.

There are MT4 EA/script generators here, here and here, of sorts, if you want to take a look at them. I haven't attempted to use any of them, hence I can't comment further.

The Forex Expert Advisor software is what I am talking about. $89 isn't too bad either, except for right now, I am not ready to take my trading system that far. Nonetheless, I bookmarked the site, thank you.

As for Clarion or Crystal Reports for that matter, I haven't used either. I only get to install and support Crystal for my customers. As for 1997, that's a long time ago my friend!

Back in 2001, when I was needing to write SQL queries for my job, I frowned on Crystal Reports. It's like creating a webpage in MS Word, if you know what I mean. So whenever I can, I try to get through the code myself some way.

I took a look at the bookmarked code that you mentioned, and I think I am beginning to see how this works.

If I can repay your kindness somehow, let me know. Like let you win at a game of Starcraft (that's from 1997, right?)...

Thanks again!

Hi,
Is there perhaps an updated version of this indi? It does not work in when i attached it to the chart.

Regards,
Shane

Try the attached. It's not an updated version. I have simply recompiled the .mq4 using the old build 509 compiler, so that it compiles without errors. Make sure that you install only the .ex4 files, i.e. delete the .mq4 file you installed from post #2 (and then restart MT4). I'm running AXiTrader MT4 build 610 and it works OK for me (see screenshot).

hi,
wow hanover, very nice coding, was able to integrate your code into my fibonacci ea within just a few minutes.
there's one thing i've noticed that i'm going to try to add.
the indi updates high low x candles back every x minutes.
i'm looking for an algorithm that only updates high/low level if there is a turnaround of price. so say we had a high 20 candles back, comparing 3or5 candles and showing them to be of values like 1-2-3-2-1 building a top, and for low turnaround the opposite, 3-2-1-2-3, this could be maybe calculated using percentage variations from highest/lowest candle. e.g. if candle 2 and 4 are 20% lower and candle 1 and 5 are 30% lower than candle 3 we got a peak and vice versa.
I'll try and work that out, but would be happy to see your professional smooth coding example for that.
thanks and great library, I keept it, wonderful source code.

Thanks for your kind words. I'm trying to focus more on trading, and less on programming, nowadays. If you need help, you can always try posting in one of the "I code your indicators for free" threads, and perhaps somebody else can help you. (Or if you're willing to pay for the work, you could try MQL or elance).
