Eazy Language Indicator and Signal

Postby pschriber2 » 28 May 2012

I'm programming a signal that utilizes two Simple Moving Averages for different time frames to determine the buy/sell decision. I am taking both short and long positions and for some reason I am getting a short signal without any crossover on the shorter time horizon SMA. I was wondering if this issue can be related to using two different time horizons for a signal. Has anyone else had a similar issue? Any help would be appreciated. Here is the sample code that I am using:


Code: Select all

var0 = AverageFC( Price, FastLength ) ;
var1 = AverageFC( Price, SlowLength ) ;
var2 = AverageFC( Close of Data2, FastLength2 ) ;
var3 = AverageFC( Close of Data2, SlowLength2 ) ;

condition2 = CurrentBar > 1 and var0 crosses under var1  ; //min short
condition4 = CurrentBar > 1 and var2 <  var3  ; // day short


if condition2 and condition4 then      // min sell, daily                                                             
   Sell Short ( "Short" ) next bar at market ;


Thanks

Have you used a PLOT to verify your logic before you jump into coding your strategy?




ps. please use code tag when posting codes. I have tagged them for you in your post.

Hi yes I did. Some of the buy/exit signs lineup but others are off. For example the short signal is 2 or 3 ticks before the short indicator.

What are your chart resolutions? Which is data1 and which is data2?
What is the instrument?


Please post a chart.
Please use lines and arrows and notes on the chart to point out the logic problem.

Hey TJ,

I was using resolutions of 60 minutes and 1 day. I was able to solve the problem. It had to do with me not explicitly stating which variables were associated with data2.

i.e. vars: price1(0,data1),
var0(0,data1);
var1(0,data1);
var2(0,data2);
var3(0,data2);

var0= MVA(close of data2, length) data2;

Thanks for your help though.

One suggestion:

Avoid using generic variable names, ie var0, var1, var2, etc.,

Always use a meaningful name. eg. Open.data1, Open.data2, etc.,
This will help you to debug when your code grows in complexity.

Okay, I will keep that in mind. There still seems to be a issue with the timing of the entry/exit points for the indicators and signals. All of the indicator points seem to be correct now but a few of the signal ones seem to be off. I have attached a labeled screen capture.

need more description on the logic, what you are expecting, and what is wrong with the chart.

ps. you should make an indicator first, before jumping into coding a strategy.

in place of BUY or SELL,

Use a PLOT to make a "dot" on the chart to show that your logic is working as expected.

The entry/exit is supposed to be given by using the crossover/crossunder on the first chart, and confirming it by checking if the bottom chart (data2) confirms this trend. The top chart uses a higher resolution. If both confirm that the faster moving average is above the slower moving average, then enter a long position. On the other hand, if both confirm slower is above the faster, then short the instrument.

I did make the indicator first, and it works for all of the points. I am trying to make the signal now. The indicator is just there to confirm the entry/exit points.
