Simple Coding Help - No Promise.

[Steve]

For previous day H/L use this, afl courtesy from TJ.

Hi Steve,

I am using the same AFL. However, I do not want High/low of the candle/ wick to be treated as H/L.
See the lines marked in yellow colour. That is what I want.

Hi Josh1,

I do not have that afl, some of the coders here may help.

Code is running correctly,remove extra spaces where the error comes.

A kind request to all to use Code "#" for pasting codes so that the code does not run through the entire page.

Even in past, it has been requested several times to use [ c ode ] [ / c ode ]

i

Will you pl. explain me which line to be changed, or what actually i have to do ? I am not conversant regarding coding matter, so pl. excuse me if i am asking any naive question.
Thanks & regards.

Thanks Amitji.
But while scanning i am getting Afl error & message is as following. Now from where to remove extra space? Because on message board i wont be able to click.

HaOpen = AMA(Ref(HaClose, -1), 0.5);



// for graph collapse

for(i = 0; i <= MAPeriod; i++) HaClose
----------------------------------------^

Error 10.
Array subscript out of range.
You must not access array elements outside 0..(BarCount-1) range

Maybe you are using lower version of Amibroker

Got nothing to do with lower versions.
You need to check if you have enough bars if your original loop uses condition other than i < Barcount or i > 0 (if iterating backwards).
If you don't do so then i.e. if Barcount of some symbol(s) is just 100 but maperiod is set to 200 then you will get error.

You also need to be aware of the fact that:
1. if you apply Verify Syntax check in AFL editor or if clicking Apply button in editor then only 200 bars are used so then barcount is 200 only internally.
2. During Optimization setup period then Barcount is set to 100 bars internally.
3. it may be the case that visible barcount is lower than some set period when zooming in and QuickAFL is ON.

That's why you have to ensure that your code always executes without error.

So if your loop condition is not using standard Barcount check but looks like

for(i = 0; i < period; i++)

or

for(i = 0; i < 1000; i++)

or

for( i = BarCount - 1; i > BarCount - 1000; i-- )

etc.

Then you have add a check to ensure error free execution in every possible case, for example

if( BarCount > MAPeriod ) // first check whether there are enough bars
{
    // this loop executes only if check result is true
    for(i = 0; i <= MAPeriod; i++)
    {
        // your code here....
    }
}

Nehal and Amitrandive are talking about adding code tags if posting AFL codes to ensure that:

1. thread pages become better readable if adding hundreds or thousands of lines of code into forum.
2. inserted code becomes better readable
3. code does not lose its original format.
4. code is "syntax error free" when copy&pasting it from forum into AFL editor. It is NOT ensured if you don't use code tags!

It takes just one second to add code tags. Just ONE.

Hi Seniors,

I am stuck with unique problem in amibroker 5.60 and 5.70 both:


When i find error in data ...use to edit data for that day...but lately when i do that on EOD database it changes format from YMD to DMy...like 2015 28 05 to 28 05 2028...extra quote get generated and database for TOSS...

Pls guide me for the same.

Same trouble fot stock split ..

Dear Friends & Respected Coders..
Good Evening...
I need Stochastic indicator in CANDLESTICK (OHLC) format for Amibroker..
I tried to search on net but failed..
Due to lack of programming knowledge, I tried to code it, but couldn't succeed.
At motivewave site I found something similar, Is it Stochastic indicator in candlestick format..??
any help would be greatly appreciated..
Thanks..

hello guys, my knowledge in coding/AFL is zero. please, convert my excel formula into an AFL. thanks in advance.

Bro U want Stochastic in OHLC or u want stochastic colored Candle sticks as u shown in pic.
the pic u shared is not of OHLC stochastic
it gives green bar as stoch crosses 20 and so on
