[mastermind007]

Sirs,
Pls Give a script (Java or other) for Auto saving RT data to Amibroker default DataBase and also to an Additional DataBase in a Different Drive & Folder.

Thank u
Shiraj

This is JScript code that will invoke Save thru COM

var oAB = new ActiveXObject("Broker.Application");

oAB.LoadDatabase( "C:\\Program Files (x86)\\Amibroker\\Data" );
///....
/// Do your stuff here .....
///...
oAB.SaveDatabase( );

I want afl to plot high/low of 1st weekly bar of the month.

sample code written for 1st hourly bar is as below

TimeFrameSet(inHourly);
up=ValueWhen(TimeNum()==101459,H,1);
dn=ValueWhen(TimeNum()==101459,L,1);
TimeFrameRestore();
up1=TimeFrameExpand(up,inHourly);
dn1=TimeFrameExpand(dn,inHourly);
Plot(dn1,"dn line",colorBlue,styleDots);
Plot(up1,"up line",colorBlue,styleDots);


I want same code for 1st week bar high/low

I request and require

1st Condition......110 candle Maximum high / Minimum low marking / deduction....

2nd Condition.....if the next candle close is below Maxium High (1st Condition) candle low...we should have marking or sell Singal.....vis versa if the next candle close is above the Minimum Low (1st Condition) Candle high...we should have marking or Buy Signal...

Can anybody help in this......

Can I directly fire orders from my AFL script ( not through charts) to Nest trader using Nest Plus API?

Is it necessary that charts need to be open always to fire the order from Amibroker to Nest Trader.. How to fire orders from generated scan results of AFL??

Yes

Is it necessary that charts need to be open always to fire the order from Amibroker to Nest Trader..

No

How to fire orders from generated scan results of AFL??

Similar to approach you'd take on chart

The basic definition of an 'up' fractal is a bar high that is both higher than the two bars immediately preceding it
and higher than the two bars immediately following it.
The lows of the bars are NOT considered in determining the up fractal progression.

If two bars in the progression have equal highs followed by two consecutive bars with lower highs,
then a total of six bars rather than the usual five bars will make up the progression.
The first High becomes the counting fractal. Reverse for 'down' fractals.

The 5 bar formation works best on Daily or longer time frame charts.For intraday data charts we often use 9 bar, 13 bar and 21 bar formations for fractal counting
