hi senior users of Amibroker & its Formulae Language,

you might have developed some code for your use.
it would be nice if you share it with fellow-members and also provide links for the internet resources for the same.

thanks in advance.

Hi Roshanna,

Please go to the amibroker news letter No. 4 and read about assigning industry groups etc. The link is http://www.amibroker.com/newsletter/04-2000.html
If you are not familiar with the programming read the first news letter.

Hi friends,

Here are some simple AFL's for the three types of stoploss - Initial, Breakeven and Trailing stoploss.

1. Initial stoploss

/************************************************** **
Initial Stoploss - lowest "low" of the last n bars
************************************************** ***/
lookbackPeriod = Param("Lookback period", 2, 2, 30);
Plot(LLV(L,lookbackPeriod), "Testing", ParamColor( "Long", colorGrey40));

2. Breakeven stoploss

/************************************************** *****
Breakeven Stoploss - Open + brokerage% of open
************************************************** ******/
brokeragePercentage = Param("Brokerage Percentage", 1, 0.1, 5, 0.1);
Plot(O + O*(brokeragePercentage/100) , "Testing", ParamColor( "Long", colorYellow ));

3. Trailing stoploss

/************************************************** **
Trailing Stoploss - a% below nth highest high
************************************************** ***/
lookbackPeriod = Param("Lookback period", 10, 2, 30);
stoplossPercentage = Param("Stoploss Percentage", 5, 0.2, 10, 0.2);

Plot(HHV(H,lookbackPeriod) - HHV(H,lookbackPeriod) * (stoplossPercentage / 100), "Bullish SL", ParamColor( "Long", colorGrey40));
Plot(LLV(L,lookbackPeriod) + LLV(L,lookbackPeriod) * (stoplossPercentage / 100), "Bearish SL", ParamColor( "Short", colorGrey40));

I will post the AFL's as and when I come up with any new ones.
Thanks,
Praveen.

Close < 10 SMA and Close > 30EMA
ADX (14) > 30 , Willims%R (3 day) < - 80

Hi Niranjanam,

An attempt from another newbie

: -

Code:

_SECTION_BEGIN("SwingPullbacks");
function PercentR( periods ){
 return -100*( HHV(H, periods) - C) / (HHV(H, periods) - LLV(L, periods)); 
}
Buy = (  (C>50 AND V > 100000) 
	AND ( C < MA(C,10) AND C > EMA(C,30) )  
	AND ( ADX(14)>30 ) AND (PercentR(3) < -80) );
_SECTION_END();

I dont understand your last 2 conditions..
.. is that -80 ???
.. 2 to 5 days ???

Regards
Siva
