TechTrader With AmiBroker

[Peakey]

Ok, i've got AmiBroker up and running, I'm currently using data from PremiumData. I'm using the following code:

*********************************
// techtrader v2 amibroker version
// here we define buy conditions and name each one as a variable
PositionSize = -10; // always invest only 10% of the current Equity
cond1=Cross(H,Ref(HHV(H,10),-1)); // when todays high crosses last highest high over the last 10 periods
cond2=H > EMA(C,40); // todays high is greater than the 40 day Exp MA of closes
cond3=HHVBars(H,70) == 0; // todays high is the highest for 70 periods
cond4=EMA(V*C,21) > 500000; // ensure at least $500k of money flow
cond5=C < 10.00; // only trading in stocks less than $10
cond6=C > O; // todays close higher than open

// the following line is the trigger if all conditions satisfied
Buy=cond1 AND cond2 AND cond3 AND cond4 AND cond5 AND cond6;

// here we define variables used once in the trade
ApplyStop( stopTypeLoss, stopModePercent, amount=10 );
Sell= Cross(Ref(EMA(L,180),-1),C); // close crosses below yesterdays average of the low
// here we define what gets displayed on the chart
shape = Buy * shapeUpArrow + Sell * shapeDownArrow;
PlotShapes( shape, IIf( Buy , colorYellow, colorRed ), 0, IIf( Buy , Low, High));

Filter = Buy; // lists exploration results conforming to our buy criteria
AddColumn(Buy, "buy", 1.0); //
***********************************

Did a scan of EOD for 14/12/2006 across the entire ALL Ords and got back the following:

**************************
ABS Buy 14/12/2006 $8.620
AED Buy 14/12/2006 $4.290
AOE Buy 14/12/2006 $1.220

SGL Buy 14/12/2006 $0.420
TLS Buy 14/12/2006 $4.060
**************************


I want to ensure my setup is correct, so I was just wondering if someone could run a scan so that I can compare results.

Thanks
Peakey

Even though it is a long time between drinks on this one I am using this same formula to try and teach myself a bit about how Amibroker works, I thought I read somewhere else that Tech A is not allowed to talk about this system or something because it has been deemed as giving advice but I'll try anyway.
I have found some other basic formuals on the Amibroker Finance Yahoo group and in this forum but from what I have read TechTrader worked at some stage during a decent uptrend and should be a valuable teaching tool for the basics of how a trading system could work. At the moment the market seems to be consolidating and as such Techtrader probably wont work too well so I cant see any ereason for a discussion on it to be a big deal.

Anyway I am not trying to find the holy grail just some Amibroker education while I wait for Howard Brandy and crew to return to the States so they can start sending out "Intro to Amibroker" again. My current question is this; I have run TechTrader V2 for Amibroker and I get a list of buys and sell in the scan and backtest but I dont seem to get any arrows showing up on the individual charts. Is there something wrong with the way the formula is written when it has been converted from Metastock language?

Danno,

You should get arrows with that code but when you run a scan click on the stock that comes up in the scan this will bring the stock up on your charts with the buy & sell arrows on it - or at least it should.

Thanks for the reply Nomore4s, I have been getting sell arrows (pointing down) and have been able to change the colour to prove I am getting something right but I dont get and buy arrows (pointing up). My sell arrows are on the company equity indicator graph, is this where they should be? I just straight cut and paste the formula off Peakeys post at the top of this thread. Does that normally work? I would have thought that the buy/sell arrows would be on the price chart rather than on the other indicators.

I tried to copy the AFL again and got the same result...maybe I will just have to wait until I can get a copy of Intro to Amibroker...

I was going to get Nick Rdges book about the Aussie market also, it seems to get a good review or two on this forum

Cheers
Danno

Last night I partially solved my problem of not being able to see the buy and sell arrows. I was testing some AFL's from the Amibroker Knowledge base and one of them but a new indicator graph below the current indicators on my first tab (below the portfolio equity indicator) which showed the buy and sell signals. I am not sure why Tech Trader didn't do this but now the indicator stays there no matter what formula I use which is a bonus...now if I only knew why this happened and which part of the formula produced the new indicator I would be a step ahead.

Anyway its one more move in the right direction

Danno,

When I get home I will post up the code I use to run TT in amibroker and post up a chart with the buy/sell signals on it to give you an idea of what it looks like.

Here you go.

// techtrader v2 amibroker version
// here we define buy conditions and name each one as a variable
PositionSize = -10; // always invest only 10% of the current Equity
cond1=Cross(H,Ref(HHV(H,10),-1)); // when todays high crosses last highest high over the last 10 periods
cond2=H > EMA(C,40); // todays high is greater than the 40 day Exp MA of closes
cond3=HHVBars(H,70) == 0; // todays high is the highest for 70 periods
cond4=EMA(V*C,21) > 500000; // ensure at least $500k of money flow
cond5=C < 10.00; // only trading in stocks less than $10
cond6=C > O; // todays close higher than open

// the following line is the trigger if all conditions satisfied
Buy=cond1 AND cond2 AND cond3 AND cond4 AND cond5 AND cond6;

// here we define variables used once in the trade
ApplyStop( stopTypeLoss, stopModePercent, amount=10 );
Sell= Cross(Ref(EMA(L,180),-1),C); // close crosses below yesterdays average of the low
// here we define what gets displayed on the chart
shape = Buy * shapeUpArrow + Sell * shapeDownArrow;
PlotShapes( shape, IIf( Buy , colorYellow, colorRed ), 0, IIf( Buy , Low, High));

Filter = Buy; // lists exploration results conforming to our buy criteria
AddColumn(Buy, "buy", 1.0); //
Filter = Sell; // lists exploration results conforming to our buy criteria
AddColumn(Sell, "sell", 1.0); //

// This section creates the data that you can plot to see how often TT2 trades
// NOTE:- Using VOLUME array so get correct number when switching to WEEKLY or MONTHLY display
AddToComposite(Buy,"~TTBuys","V");
AddToComposite(Sell,"~TTSells","V");

Buy = ExRem(Buy,Sell) ;
Sell = ExRem(Sell, Buy);
Binary = Flip(Buy , Sell);

No worries, the scan I ran was from the 1/10/09 to 30/10/09 over the All Ordinaries and AAX was the first stock on the list, let me know how you go.

NM4's,
I copied Tech Trader straight from your post but the first I got was AAD, also I can't get the buy sell arrows to show on my primary chart. They will only appear on the lower indicator that consists of an advanced MA AFL that I was playing around with last night. I don't actually know how it managed to appear but it stays on whenever I shutdown and restart. I am not sure how to attach a screen print of Amibroker other wise I would show you. My second listing was the same as yours AAX but had an extra sell (27/4) and an extra buy (02/06) so I'm not sure what that is all about.
