Can senior members provide color coding for the same: like Blue for hollow candles with upper shadows, Red for filled candles with lower shadows and diffrent color for body with lower and upper shadows?

If the information is already available, can you provide a link to it.

Kindly also add Buy and sell signals with arrows and prices.

Hi SRJC,

In case I have understood it correctly.... just replace the following line

barColor = IIf(HaClose > HaOpen AND HaHigh > HaClose AND HaLow < HaOpen, ParamColor("Up with both wick, Color",colorBlue),
IIf(HaClose < HaOpen AND HaLow < HaClose AND HaHigh > HaOpen, ParamColor("Down with both wick, Color",colorViolet),
IIf(HaClose < HaOpen AND HaLow < HaClose, ParamColor("Down Color",colorRed),
IIf(HaClose > HaOpen AND HaHigh > HaClose , ParamColor("Up Color",colorGreen), colorWhite))));

PlotOHLC( HaOpen, HaHigh, HaLow, HaClose, "Modified " + Name(), barColor, styleCandle | styleNoLabel );

I can help you with the Buy and sell Signal... but you need to tell me the exact condition when to buy and when to sell.

take care.

Posting the changed AFL also..

HI dhakkan

Thank you very much. Your thoughtful coding of 'up bar with both wick' and 'down bar with both wick' had ensured the continuity of price and as such eliminated the need for price arrows.

Once again a special Thank You for your cooperation.

Difference Between Timeframe set and TimeFrameGetPrice Function
Hi all ,
I am trying to put hourly Ema in 15min Chart but I cant understand which one should be used.

I wrote 2 codes:
1.

EMAstyle=ParamStyle("MAType",styleLine,maskAll );
EMAperiod=Param("MA Period",13,10,500);
ChartStyl=ParamStyle("Chart Type", styleCandle,maskAll );
Chartcolor=ParamColor("Chart Colour",colorBlack);

C_hrly=TimeFrameGetPrice("C",inHourly,0);
splema=EMA(C_hrly,EMAperiod);

Plot(splema,"Hourly EMA of "+EMAperiod+" Bar",colorBlue,EMAstyle);

2.

EMAstyle=ParamStyle("MAType",styleLine,maskAll );
EMAperiod=Param("MA Period",13,10,500);
ChartStyl=ParamStyle("Chart Type", styleCandle,maskAll );
Chartcolor=ParamColor("Chart Colour",colorBlack);

TimeFrameSet(inHourly);

HourlyEMA=EMA(C,EMAperiod);

TimeFrameRestore();
Plot(TimeFrameExpand(HourlyEMA,inHourly),"Hourly EMA",colorPink);

The problem is that, two ema values are different.
Please tell me which one can be used as actual hourly ema?

I ploted a normal ema by using Drag drop from average list in the amibroker.
after converting the chart into hourly mode , above two codes show same value but they are diff from the normal ema.
If any one of the above two codes results hourly ema then atleast 2 ema should be same after converting the chart into hourly mode.
Please Help. I am very much puzzled.
regards

Hi senior members and experts. I'm new to Amibroker and the AFL language is a bit daunting to me. I was wondering if any of you fine gentlemen or women - as the case may be - might be able to help me out here.

I'm trying to combine two or more afl formulas to generate a single exploration. Firstly : Is it possible?

If at all possible, how does one go about making a single afl file that can have many variables in it?

I mean, I can find different afls for all of the scans, but I would like to combine them into one. I can manage with a little bit of programming, so a little nudge from the experts ought to do it. Oh! and I'm sorry if this is a repeat query.

Looking forward to your expertise and assistance

Yes you can. Just copy the AFL's under the one you need the plot. Add the columns you need the exploration result with their formule. Alternatively you can give buy1, buy2...and display under different columns.

Explore and see the result.

Regards
ken

HI dhakkan

The following is the

Trailing Stop - ATR Chandelier Exit v2.0 in MetaStock formet from trader on line.

delay:=Input("Entry and Exit signal delay",
0,5,0);

If(plot=1,stop,
If(plot=2,Ref(stopLong,-1+adv),0));
If(plot=1,stop,
If(plot=2,Ref(stopShort,-1+adv),signals))<<<<<<<<<<<<
Can you please get it converted into AB AFL with Buy/Sell Signals, crossing the closing price?

There are about a dozen “trailing stop loss” indicators in the above portal and this is the best indicator.

Thanks in advance
