Need little help with a Ninjatrader script

April 20th, 2011, 02:55 AM

Hi All,
I need to code few simple lines but not sure how to do it. I'd appreciate any help.

1) RSI(14) has been above 80 anytime within last 12 bars.

2) And price is at least 20 pips above the SMA(25)

Thanks.

hi raindrop,

i think a little more explaination of what you like to have is needed for helpers.
do you work on an indicator or strategy ?
do you want to plot anything ?
do you only want to have the conditions to be written in code ?

thanks

dont know if this is the most elegant way to do, but you can try something like below

put the code in OnBarUpdate

Code

bool istrue = false;
            
 for (int i = 0;i<= 11; i++)
 {
           if (RSI(Close,14,3)[i] > 80)
          {
                    istrue = true;
                    break;
           }
 }

if (istrue && Close[0] - TickSize * 20 > SMA(25)[0])
{
   //do your stuff

}

You can also look at MostRecentOccurance()/LeastRecentOccurance() for the RSI part of the logic.

thanks MXASJ, thats the way to go.

what you guys think about the count If - code for the RSI - check ?

// If in the last 10 bars we have had 8 up bars then go long

if ( CountIf(delegate {return Close[0] > Open[0];}, 10) > 8)

.... do things

Unless I am missing something...

if (MAX(RSI(14), 12)[0] > 80 && Close[0] > SMA(25)[0] + 20 * TickSize)
// Do something

boy o boy

now whos the fairest of all

my code (post 4) and the one posted by Ray using the MAX function are essentially the same. my code breaks from the loop once the condition is fulfilled (i.e. RSI > 80) while MAX loops to the end and find the highest value. So that way max is doing some extra loop which is redundant in our case.

what is the code behind MRO as MXASJ pointed out?

I came back to see if there is any response to my question and was amazed to see the level of help here. I really appreciate everyone trying to help me here.

I am trying to write a trend trading strategy script so that's why I want to look back few periods. I do not have to plot the RSI on the chart but it would be a plus if I could. I can write simple scripts on Stockfetcher but that is the limit of my coding abilities

.

Now while testing my strategy I have noticed that price is more likely to whipsaw when it is very close to lets say SMA(25) and I want the strategy to only generate a signal if price is at least 25 pips away (above or below depending upon the direction of the trade) from SMA(25). What would you experts think such a script look like?

Again I appreciate all the help extended to me in this thread.

Raindrop.
