Chaitanya,
 
not exactly sure if I have understood your system but here is my interpretation below. When in a long term uptrend the price moves down 5 consecutive bars and then closes green including a higher high is set then buy the next bar at the open, similar story for short,
 
Ed
 
 
per =220;

// use map for the trend indicator

map =
MA(C,per); dmap = map - Ref(map,-1
);

// number of downbars

tt = NumDownBars =
BarsSince( C >= Ref(C,-1
));
// number of up bars

ss = NumUpBars =
BarsSince( C <= Ref(C,-1
));

// buy constraint: down 5 bars in a row, then last bar high greater than previous high, trend is up

bc1 =
Ref(tt >= 5,-1) AND H > Ref(H,-1) AND C > Ref(C,-1) AND dmap > 0
;  
Buy
= bc1;
Buy = Ref(Buy,-1); BuyPrice = O
;

sc1 =
Ref(ss >= 5,-1) AND L < Ref(L,-1) AND C < Ref(C,-1) AND dmap < 0
;
Short
= sc1;
Short = Ref(Short,-1); ShortPrice = O
;

SetChartOptions(0, chartShowDates
);
GraphXSpace = 5
;
Plot(C,"C",1,64
);

PlotShapes(IIf(Buy,shapeUpArrow,0),colorWhite, layer = 0, yposition = BuyPrice, offset = 0
);
PlotShapes(IIf(Short,shapeHollowDownArrow,0),colorLightBlue, layer = 0, yposition = ShortPrice, offset = 0 )
;

Subject: [amibroker] How to wait for the Top or Bottom of the previous bar to be taken out?

Hello all,

How can i code something like this (presented in Oliver Valez
presentations):

For short setup:

1. Wait for 3 bars to close green (above yesterdays closes for 5
days).
2. Now basically sell (short) when the next bar closes below the Low
of the previous bar.

reverse for long setup.

I can check for 5 bars to close green using

BuySignal = (C > Ref(C,-1)) AND (Ref(C,-1) > Ref(C,-2)) AND (Ref(C,-
2) > Ref(C,-3));

Buy = BuySignal;

But how do i make it wait for the previous bars low to be taken out
before going short.

Additionally: use the setup in the direction of the prevailing trend
or some other filter on top of this setup

thanks
Chaitanya.
