Can anyone tell me how to enter ASX stock symbols into Amibroker while using Interactive Brokers data? Eg. WBS-ASX-STK??? obviously not as that doesn't work, but it should be something like that.

Cheers,

Is there any way to compress a chart so that all the historical data can be seen at once?

Click the "Zoom Out" icon on the right side of the chart window.

Or

Drag the left boundary of the slider at the bottom of the chart window.

You can go to 'View' - 'Zoom' - 'All'. There is no shortcut key for this by default, but if you want to you can assign pretty much any function to a shortcut key of your choosing. Go to 'Tools' - 'Customize' - then click the 'Keyboard' tab.

Alternatively you can hold ctrl while scrolling your mouse wheel. Although for some reason that won't zoom you out far enough to see all the available data.

I'm also wondering how to display the open, high, low and close across the top of the chart as well as the % change for the day?

I've got this code from another chart which displays what I want. I've tried adding this to the new chart but it still isn't working. Does anyone know why?

_SECTION_BEGIN("Super Trend ");
SetChartOptions(0,chartShowArrows|chartShowDates);
_N(Title = StrFormat("{{NAME}} - {{INTERVAL}} {{DATE}} Open %g, Hi %g, Lo %g, Close %g (%.1f%%) Vol " +WriteVal( V, 1.0 ) +" {{VALUES}}", O, H, L, C, SelectedValue( ROC( C, 1 )) ));
Plot( C, "Close", ParamColor("Color", colorBlack ), styleNoTitle | ParamStyle("Style") | GetPriceStyle() );
if( ParamToggle("Tooltip shows", "All Values|Only Prices" ) )
{
ToolTip=StrFormat("Open: %g\nHigh: %g\nLow: %g\nClose: %g (%.1f%%)\nVolume: "+NumToStr( V, 1 ), O, H, L, C, SelectedValue( ROC( C, 1 )));
}
_SECTION_END();

Does anyone have the database Intraday settings for US stocks. I am having problems with getting the daily data derived from the intraday to match.
The problem arises from the time difference, as the start of trading begins at 11.30pm and crossover to the next day where it finishes at 6.00am.
I have tried various combinations and have not been able to get it correct.
With the attached settings it seems to get most of it right except the opening time. It is using 9.31am's opening time for the day but other chart providers like Google and ESignal are using the opening for 9.30am.

For eg. 2/9/11 eSignal has opening value for AAPL @ 374.74 but Amibroker is showing 375.06

tminus · 3 September 2011

Edit the problem only seems to be with AAPL, others are showing the 9.30am data

Deleting AAPL symbol and re-adding it doesn't fix it, and cleaning up the database isn't working

G'day all

I am reasonably new to Amibroker and have a minor issue I can't seem to fix.

Attached (hopefully) is a chart which has a pale blue liear regression line drawn over approximately the last 21 bars. Problem is I don't think I put it there - if I did it was a mistake. How do I remove it ?

Thanks in advance

Paul

To remove the linear regression section of the formula, one way is to right click in the top right hand corner of the chart (inside the y-axis) and there should be a drop down box with "delete linear regression" or something similar. Click on the "delete linear regression" part and that should remove it.

Otherwise, right click anywhere on the chart and select "edit formula". This will open the formula in the formula editor. Right click on the formula, select "select all" then right click again and select "copy". Paste the formula here in between code tags and me or someone else will show you which section to delete.

...and, welcome to Amibroker

Here's the relevant tutorial section. The "How to remove indicator plot from the pane" part is what I outlined in my first part above.

G'day Captain

Thanks for the reply. I tried something that fixed the problem before I read your post...

- Right click on the chart pane
- Select "Delete indicator"
- Only option was "Price" so I deleted that (empty chart with no price bars)
- Closed the chart pane
- Opened a new chart pane with "Price" only (no regression line, all appears OK)

Your explanation suggests that the regression line was part of a formula which I must have attached to the chart without understanding what I was doing - quite possible, but I am improving.

Thanks again

I am trying to apply an index filter, but can't seem to get it right. In this case I am simply buying/selling when a stock crosses its 60MA, but I don't want it to generate a Buy unless ^AORD closed above its 200MA.

Code:

PositionSize = -5;

index = "^AORD"; 

if ("^AORD" == Close > MA (Close, 200))
{
Buy = Close > MA(Close, 60);
}

Sell = Close < MA (Close , 60 );

Also, do I include the ^AORD ticker in the same ticker list as the stocks I am testing? Or do I keep it separate somehow as I am not actually buying/selling the index?

You need to access the Index using either Foreign or SetForeign. Example below:

Code:

SetForeign( "^AORD",True,True );
Buyfilter = Close >MA( C, 200 );

RestorePriceArrays(True);

Buy =  C > MA(C,60)  AND Buyfilter;

It pays to tick the "Pad and Align Data to reference symbol" (and insert your reference Index symbol) in the AA settings.

There's no need to have the your index symbol in the watchlist you're testing.

That makes sense! Thank-you Captain Black

I have the foreign referenced ticker symbol in the database being referenced. For example I have ^AORD & ^GSPC as ticker symbols in my All Ords stock list.
If you don't have the ^AORD symbol data in your database the backtest won't return any trades.

That's correct, the index symbol needs to be in the same database as the symbols you're testing but doesn't need to be in the same "ticker list" (I assumed Gav meant watchlist).
