Comment on How to migrate AmiBroker to a new computer by Herman

Herman — Tue, 29 Mar 2011 08:43:54 +0000

Hello Marcin,

It often happens I need to copy the AmiBroker system to another computer from, or to, another drive letter.

Could you also explain what the potential problems are, and what is the best way to do that?

Thanks,
herman

Comment on Low-level gfx example: Yearly/monthly profit chart by K Riemer

Is there anyway to automate the export of a single named chart (similar to “Edit->Image->Export to file”) through JavaScript or AFL?

Regards

Comment on How to create copy of portfolio equity? by Paolo

It would be great to have an AFL formula to get the afl file name (somethink like GetAFLName) in order to automatically append it to the new ticker name
i.e. AddToComposite( Foreign(”~~~EQUITY”,”C”),
“~~~MY_EQUITY_COPY” + GetAFLName(), “X”,
atcFlagDeleteValues | atcFlagEnableInPortfolio );
This would allow to have different equity curve saved with proper names

Comment on How to detect the study crossover for multiple symbols with use of SCAN by Tomasz Janeczko

Yes but you need to have 2 separate IDs. TO assign different IDs use Properties window.
By the way: you will get much faster responses if you use support at amibroker.com e-mail. Thank you.

Hi Tomasz,
In the example there is 1 trendline drawn. Is it possible to have 2 trendlines drawn on the same chart and have AB find similar patterns? In the example chart if another trendline was drawn across the lows it would look like a descending wedge would it be possible to use this study to find triangular patterns and assign each one a study ID? Thank you.

Thank you Tomasz. Do I manually have to draw a trendline on every chart or will the software look for that kind of trendline pattern on the stock list I select? I am attempting to scan my list of stocks for triangles and rectangle patterns before they breakout. Then with an alert of some kind I can be ready to trade the breakout. Thank you for any and all help.

You can have different trendlines with different StudyIDs. You can simply type different study ID in its entry field.

Do you have to use the same symbol to draw different trendlines or can you use different symbols utilizing different trendlines? I am particularly interested in scanning for such trendlines before they are broken and utilizing an alert to tell me when they are broken intraday, is this possible?

Comment on Discretionary Equity by Tomasz Janeczko

Please note that this formula uses Equity() function, so it will use any Automatic Analysis setting that you have defined, including “Positions” and “Trade Delays”.
Make sure to set delays to zero in the settings or use SetTradeDelays( 0, 0, 0, 0 ), otherwise delays defined in the settings will be applied.
The same applies to “Positions” setting. Make sure it is set to handle Long and Short positions if you want to take both.

Comment on How to plot a trailing stop in the Price chart by Tomasz Janeczko

Tomasz Janeczko — Wed, 30 Jul 2008 11:30:16 +0000

For “point” mode replace
StopLevel = 1 – Param(”trailing stop %”, 3, 0.1, 10, 0.1)/100;
with
StopLevel = Param(”trailing stop pt”, 3, 0.1, 10, 0.1);

and every occurrence of:
High[ i ] * stoplevel

with
High[ i ] – stoplevel
