Param+SetOption question

[jb]

Tring to post a new message but for some reasons does not go thought. Please see below. Useful if we could open a new tread.

I have used two approaches in the preparation of the code snippets below.
Code Set1 to Set20 are unique. All the codes below Set20 use the same structure:

option="NAME OF THE SET OPTION";
Set=Param(Option,0,0,100,1); SetOption( Option,Set);

testing them before sharing in amibroker forum.

Have I made any huge mistake?


Set1 = ParamToggle( "NoDefaultColumns", "FALSE|TRUE", 0 ); // if set to True - exploration does not have default Ticker and Date/Time columns
SetOption( "NoDefaultColumns", Set1 ) ;

Set2 = Param( "InitialEquity", 10000, 0, 1000000, 1 );
SetOption( "InitialEquity", Set2 ) ;

Set3 = ParamToggle( "AllowSameBarExit" , "FALSE|TRUE", 0 );
SetOption( "AllowSameBarExit", Set3 ) ;

Set4 = ParamToggle( "ActivateStopsImmediately" , "FALSE|TRUE", 0 );
SetOption( "ActivateStopsImmediately", Set4 ) ;

Set5 = ParamToggle( "AllowPositionShrinking" , "FALSE|TRUE", 0 );
SetOption( "AllowPositionShrinking", Set5 ) ;

Set6 = ParamToggle( "FuturesMode" , "FALSE|TRUE", 0 );
SetOption( "FuturesMode" , Set6 ) ;

Set7 = ParamToggle( "InterestRate" , "FALSE|TRUE", 0 );
SetOption( "InterestRate" , Set7 ) ;

Set8 = Param( "MaxOpenPositions", 10, 0, 1000, 1 ); // maximum number of simlutaneously open positions (trades) in portfolio backtest/optimization
SetOption( "MaxOpenPositions", Set8 ) ;

Set9 = ParamToggle( "WorstRankHeld" , "FALSE|TRUE", 0 ); // the worst rank of symbol to be held in rotational trading mode (see EnableRotationalTrading for more details)
SetOption( "WorstRankHeld" , Set9 ) ;

Set10 = Param( "MinShares", 1, 0, 1000, 1 ); // the minimum number of shares required to open the position in the backtester/optimizer. If you don't have enough funds to purchase that many, trade will NOT be entered
SetOption( "MinShares", Set10 ) ;

Set11 = Param( "MinPosValue", 1, 0, 1000000, 1 ); // (4.70.3 and above) the minimum dollar amount required to open the position in the backtester/optimizer. If you don't have enough funds trade will NOT be entered
SetOption( "MinPosValue", Set11 ) ;

Set12 = "0-commission table,1-percent of trade,2-$ per trade,3-$ per share/contract";
CommModetog = ParamList( "Report Mode:", Set12, Defaultval = 2 );

for( n = 0; ( Mode = StrExtract( Set12, n ) ) != ""; n++ ) {
   if( Mode == CommModetog )
       break;
}

SetOption( "CommissionMode", n );

Set13 = Param( "CommissionAmount", 0, 0, 1000, 0.1 ); // amount of commission in modes 1..3
SetOption( "CommissionAmount", Set13 ) ;

Set14 = Param( "AccountMargin", 100, 0, 100, 0.1 ); // account margin requirement (as in settings), 100 = no margin
SetOption( "AccountMargin", Set14 ) ;

Set15 = ParamToggle( "PriceBoundChecking", "FALSE|TRUE", 0 ); // if set to False - disables checking and adjusting buyprice/sellprice/coverprice/shortprice arrays to current symbol High-Low range.
SetOption( "PriceBoundChecking" , Set15 ) ;

Set16 = ParamToggle( "ReverseSignalForcesExit", "FALSE|TRUE", 1 ); // reverse entry signal forces exit of existing trade (default = True )
SetOption( "ReverseSignalForcesExit" , Set16 ) ;

Set17 = ParamToggle( "UsePrevBarEquityForPosSizing", "FALSE|TRUE", 0 ); // Affects how percent of current equity position sizing is performed. False (default value) means: use current (intraday) equity to perform position sizing, True means: use previous bar closing equity to perform position sizing
SetOption( "UsePrevBarEquityForPosSizing" , Set17 ) ;

SetOption( "UseCustomBacktestProc" , Set19 ) ;

Set20 = ParamToggle( "EveryBarNullCheck", "FALSE|TRUE", 1 ); // allows to turn on checking for Nulls in arithmetic operations on every bar in the array(by default it is OFF - i.e. AmiBroker checks for nulls that appear in the beginning of the arrayand in the end of the array and once non-null value is detected it assumes no further holes (nulls) in the middle). Turning "EveryBarNullCheck" to True allows to extend these checks to each and every barwhich is the way 4.74.x and earlier versions worked. Note however that turning it on gives huge performance penalty (arithmetic operations are performed even 4x slower when this option is ON, so don't use it unless you really have to).
SetOption( "EveryBarNullCheck" , Set20 ) ;

I have moved your post to new thread.

What do you mean by

Tring to post a new message but for some reasons does not go thought.

Do you mean you can not post new thread?

For testing forum functionality please go to here amibrokerforum.proboards.com/board/27/testing-area or send PM to me.
Otherwise we would end up with endless thread hijackings and post movements.

Also please consider using code tags next time. They are there for a a good reason.
Again for testing forum features use upper linked testing area.

Thank you!

[jb]

yes, I could not post a new thread. I understand that I have to post in testing area first.
Will do next time, thanks for helping.

[Admin]

I have just checked in admin area and there are not restrictions for members to create threads. Please PM me about what you were trying to do (which area of forum and which steps you did).

Thanks

jb, avoid using param functions in analysis. you will face problems more sooner than later. use hardcoded settings. you may use them for explorer (I do that too) but for backtest ...nope. if backtesting you want to be sure which setting has been used. this is assured only if they are hard coded.


and once again chartid in analysis is always zero. param functions rely on chartid because they were designed for chart panes. so if chartid is always zero it will cause problems if params have same description. if set in one analysis it will be set in other analysis to same setting if same param. et voila there it is the first problem.

ok, understood. I do not use AB for charting. Only for explorer. Won't use them with back testing and optimization.
Will follow your tip.
Thanks a lot for you help.
