Help with MA mean Reversion strategy

February 4th, 2019, 07:43 AM

I need help to program a part of a strategy in easy language. The part I need help with is how to calculate the % difference between 2 SMA. Below is copy from the strategy in text

Thanks

"when the 2 period moving average begins to move away from the 5 period moving average it�s analogous to a jaw being opened. Once the gap between the two moving averages exceeds 3% an entry condition occurs, "

Rosenberg12,

welcome to futures.io. Your code has access to the average values, so you should be able to compute the percentage the faster SMA is above/below the slower SMA using math. You might want to post the code that you have, so others can point you in the right direction.
Then you can monitor the percentage and either allow an entry when the difference is > X % or only on the bars where the difference crosses over X.

Bellow is what i have got so far. Tt is the part in condition1 where i have only made % that i am not sure how to solve

inputs: Price( Close ), SlowLength( 5 ), fastLength (2) ;
variables: var1( 0 ), var2( 0 ), var3 (0) ;

var1 = Average( close , SlowLength );
var2= Average( close , fastLength );
// var3 = (var1 - var2)/100 ;

condition1= var2 is 3 % or more from var1 :

If condition1 then buy this bar on close ;

IF barssinceentry = 3 then sell this bar on close;

Rosenberg12,

computing the percentage difference between two averages is the same as for example computing the percentage difference between two stock prices or any two values for that matter.
You could compute it as:
( Fast Average - Slow Average ) / Slow Average

To make your programming life easier I would suggest using meaningful variable names, as this will make your code much easier to read.

Hellow

Bellow is the code i came up with not sure if it is correct

inputs: Price( Close ), SlowLength( 5 ), fastLength (2) ;
variables: var2( 0 ), var1( 0 ), var3 (0) ;

var1 = Average( close , SlowLength );
var2= Average( close , fastLength );
var3= ((var1-var2)/var1)*100 ;

condition1= var3 >=3;

If condition1 then buy this bar on close ;

condition2= var2 > var1;

if condition2 then sell this bar on close ;

Hi Rosenberg12,

a good way to check if the code is doing what you have in mind is to use the "Print" reserved word to check the internal values within your code. This can be very helpful in understanding what the code does.
Alternatively you could convert part of your logic into an indicator and plot the percentage that you computed on the same chart as the strategy is applied to.

To prevent division by 0, you might change

var3= ((var1-var2)/var1)*100 ;

to

var3= ((var1-var2)/(var1+0.00000001))*100 ;

Thansk Sharon I will try this

Rosenberg12,

you could still run into a division by zero error in the unlikely case that var1 = -0.00000001. A good coding practice within Easylanguage is to check the denominator before every division to make sure that it's not zero. In case it is, you can use an alternative value then (or do nothing and have the variable keep its current value).

Code

if var1 <> 0 then
   var3= ((var1-var2)/(var1))*100 ;
else //use an alternative  calculation
   var3= ((var1-var2)/(var1+0.00000001))*100 ;
