Access to low in BarsArray

[tonynt]

Hello,

for coding strategies including different timeframes (Add(PeriodType.Range, 15) I have one problem as I can not access the Low of a Bar in this timeframe (BarsArray[1]). How can I code correctly eg (as now I get error messages)

If Lows[BarsArray[1] [0] < EMA((BarsArray[1],15 [0])

I can compare different Bars within this BarsArray or code "Rising, CrossAbove"... but I couldn´t do "If Low of Bar < EMA(15)".

Thanks
Tony

Hello tonynt,

You use Lows[1][0] if you want to access the low of the secondary time frame.

if (Lows[1][0] < EMA(BarsArray[1],15)[0])

barsarray

hi a believe I am asking in the right place,


I am running a 60 min per bar strategy and need to add 1 min bars, I can call upon them no problem with

add(PeriodType.Minute,1); 

the question I have is that my strategy get signals as such :

onbarupdate() 
/* I get my high for the first 60 1 min bars - example from 12h00-12h59 */ 
double XX = MAX(High.BarsArray[1], 60)[0] 
/*get my high for 60 bars, (minus the first 1 min bar (12h00) and add the next one (1h00)) - 12h01 to 1h00 */ 
double XX1 =MAX(High.BarsArray[1], 60)[-1] 

/* trade */ 
if(XX > XX1) 
enterlong 

am I using the right code (barsArray)? and is the [0] and [-1] giving me what I actually want?

I know I should be tracking what this does and printing the outcomes in the output window, but if I am completely off...sad.

thanks

Hi ChanceHero,

You want to use Highs here, to access highs of secondary series.

Highs[1] //Secondary Series high. Use this as input for other indicators.
Highs[1][0] //Most recent secondary series high. Use this for parameters expecting a double as input.

double XX = MAX(Highs[1], 60)[0]

Using negative index values is not supported. You'll want to use positive index values to reference prior values.

double XX1 =MAX(Highs[1], 60)[1] //gets the highest high of last 60 bars, starting one bar prior to the bar you're calling this from.

ok getting better

Ok so I think I get it. now I have something like :

NOTE: my main bars are 60 min. my secondary bar (index 1) are 1 min bars

/* to obtain the first set of values for this just past hour example if it is 1pm now - this is getting me the 60 bars from 12h-1pm*/
            double X00Y00 = MAX(Highs[1], 60)[0];
            double X01Y00 = MAX(Highs[1], 60)[1];
            double X02Y00 = MAX(Highs[1], 60)[2];
            /* to obtain my second set of values for two hours ago - if it is 1pm now - this is getting me the 60 bars  from 11h (am) - 12h  */
            double X00Y01 = MAX(Highs[1], 60)[60];
            double X01Y01 = MAX(Highs[1], 60)[61];
            double X02Y01 = MAX(Highs[1], 60)[62];
            /* to obtain my third set of values for three hours ago - if it is 1pm now - this is getting me the 60 bars from 10am - 11am */
            double X00Y02 = MAX(Highs[1], 60)[120];
            double X01Y02 = MAX(Highs[1], 60)[121];
            double X02Y02 = MAX(Highs[1], 60)[122];
            
            if(X00Y00 < X00Y01 < X00Y02);
            {
                myEntryOrder = EnterLongLimit(0,true,1,Close[0], "LongA0"]);    
            }    
            if(X01Y00 < X01Y01 < X01Y02);
            {
                myEntryOrder = EnterLongLimit(0,true,1,Close[0], "LongA1"]);    
            }    
            if(X02Y00 < X02Y01 < X02Y02);
            {
                myEntryOrder = EnterLongLimit(0,true,1,Close[0], "LongA2"]);    
            } 

It seem that since I am only jumping 60 bars at a time, there could be a easier way to do this. Especially if I want to do the three sets but 60 times each. i.e. from X00Y00 to X00Y59 and X01Y00 to X01Y59 and X02Y00 to X02Y59 and enter the same entry logic as I have above.

thanks and have a great new year!

You could look into looping commands to simplify and run through iterations needed more efficiently - http://www.ninjatrader.com/support/h...g_commands.htm
