# Can I apply sigScaleIn sigScaleOut in Automated Trading With Amibroker?

The code below is about scale in/scale out in backtest function.
I study how to scale in/out from this link http://www.amibroker.com/members/library/formula.php?id=1380
and simplify it more easily as the basic requirement.

``````
SetOption ("InitialEquity", 100000);
SetOption ("MaxOpenPositions", 1);
SetOption ("MinShares", 100);
RoundLotSize=100;

FirstBuy = Cross( EMA( C, 10 ), eMA( C, 200 ) );
Buy2=Cross( EMA( C, 25 ), eMA( C, 200 ) );
Buy3=Cross( EMA( C, 50 ), eMA( C, 200 ) );

Sell1=Cross( EMA( C, 25 ), eMA( C, 10 ) );
Sell2=Cross( EMA( C, 50 ), eMA( C, 10 ) );

ScaleOutExExit=Sell1;

Sell=Sell2;

ScaleExit1=50;  //first Sell 50% with scale out

SetPositionSize(PosSize,spsPercentOfEquity);

``````

My question is the following.

1. Can I apply sigScaleIn sigScaleOut in Automated Trading With Amibroker such as IB
I would like to see sample code to implement in the real world rather than just BackTest.  1. For more requirementm I try to change from cross function to ">" "<" operator instead cross function as below
``````FirstBuy = EMA( C, 10 )> EMA( C, 200 );
Buy2=EMA( C, 25 )> EMA( C, 200 );
Buy3=EMA( C, 50 )> EMA( C, 200 ) ;

Sell1=EMA( C, 10 )<  EMA( C,250 ) ;
Sell2=EMA( C, 10 ) < EMA( C, 50 ) ;

``````

Unfortunately, The result isn't the same as the first one.
I understand that ExRem/Flip function may help me to complete the second code but I don't sure what step to place these code to my code , pleas guide a bit for applying ExRem/Flip to the above code

1. What level for scale in /out to need to use CBI programming? my sample may be unnecessary.
