Amibroker, Afl, simple trading system

S

stighy

Hi, hope someone could help me.. i'm trying to learn how amibroker work.
I would like to make a simple trading system, that Buy (or Alert) when price is near some moving avarage.

So i write something like:

MaxDistance=0.5;
myavarage = 200;
dist = (( Close / EMA(Close,myavarage ) )*100)-100;
Buy = iif(dist<MaxDist, 1,Buy);

// Another avarage
myavarage = 100;
dist = (( Close / EMA(Close,myavarage ) )*100)-100;
Buy = iif(dist<MaxDist, 1,Buy);

But it seems not work...
Someone expert with Amibroker can help me ?

Thank you and regards!

You have a long road ahead.
However we all need to start somewhere....

First off get the spelling right, 'average', not 'avarage' although not critical at this stage.

Second, in one same formula don't mix the same code.
ie,
myavarage = 200; & myavarage = 100; Use either one or the other, not both

thirdly, you have not completed this line of code
Buy = iif(dist

Should be something like this..

MaxDistance=0.5;
myaverage = 200;
dist = (( Close / EMA(Close,myaverage ) )*100)-100;
Buy = iif(dist < MaxDistance, 1, 0);

Filter = Buy > 0;

Just play around with the first bit of code till you get it right, then add the " // Another average " into the equation.
Always keep a sharp eye out for typos, they will stop a code working.

Just spotted another error...but it wont change much, should be
= Close / EMA(Close,myaverage )*100;
Don't need double brackets, (( )) one will do it.
 
Here's the full code....I think this should do you...


MaxDistance= 0.05; // max percentage difference required
myaverage = 200; // unit of moving average

MyEMA = EMA(C,myaverage);
dist1 = MyEMA - C; // $ difference
dist2 = (EMA(C,myaverage)- C)*100 / MyEMA; // percentage difference
Buy = IIf(dist2 < MaxDistance*100, 1, 0);

Cond1 = C < MyEMA;
Cond2 = dist2 <= MaxDistance*100;

Filter = Cond1 AND Cond2;

AddColumn(C, "close",1.3); // closing price
AddColumn(MyEMA, "MyEMA",1.3); // Chosen EMA amount
AddColumn(dist1, "$ difference",1.3); // $ difference
AddColumn(dist2, "dist2",1.3); // percentage difference
AddColumn(Buy, "Buy=1",1);

Thank you for your time !
Another question : how to "modify" that code, if i want to check another one moving average ?
I want the alert if price "touch" ma 200 and ma 50 (for example)...

Thank you again !

Sheesh, I did you a reply then my ADSL connection dropped out, so i lost my reply, trying again.

change this line...
myaverage = 200; // unit of moving average
to whatever period you want, eg...
myaverage = 50; // 50 period average

you want the alert if price "touch" ma 200 and ma 50 (for example)...
change this line...

MaxDistance= 0.05; // in this instance 0.05 = 5%
to touch line, then you want zero percent, therefore...
MaxDistance= 0.00;

I would have thought my code was quite self explanatory.

if you want it to touch both 200 and 50 EMA's, ie they come together.

myaverage = 200 AND 50; // unit of moving averages

But this will greatly limit your results
