RSI in the condition

[Stanfillirenfro]

Hello!

When the RSI is below the oversold zone, I save its value in the Series RSILow. I also save the value of the Low of the corresponding bar in the series BarLow.

The print function gives me the expected values on the output window.

The obtained values are then compared as shown in the line (a), but the print function is failing to pup up the result of the multiplication used to test if this condition is working. But when I comment the following section of the line (a)

&& BarLow[0] > BarLow[1];

, I obtain 2000.

For the line (a), why the comparison

RSILow[0] > RSILow[1]

is working alone and when combined with

&& BarLow[0] > BarLow[1];

it fails?
I have the following code in OnBarUpdate()

myRSI[0]     = RSI(Close, Amplitude,  3)[0];
if(myRSI[0] < Oversold)
{
    RSILow[0] = MIN(myRSI, barBackwards)[0];
    BarLow[0]  = MIN(Low, barBackwards)[0];

    Print("RSILow" + " Size " + ":  " + RSILow[0] + " : " + Time[0]);
    Print("BarLow" + " Size " + ":  " + BarLow[0] + " : " + Time[0]);

  if(RSILow[0] > RSILow[1] && BarLow[0] > BarLow[1])   // (a)
  {
     Print("Product" + " Size " + ":  " + 1000*2 + " : " + Time[0]);
  }
}
​

I would appreciate any help.

Thanks in advance!

Hello Stanfillirenfro,

From just the code I can't tell how this may have evaluated, do you have the prints that go with this code that show how the condition evaluated when run?

Hello NinjaTrader_Jesse and many thanks for your reply.

I have attached the prints.

Thanks!

Hello Stanfillirenfro,

It looks like you are not printing the 1 bar ago value, it would be helpful to just print all 4 values used in the condition along with the bar time so you can see why the condition is not becoming true.


Print(RSILow[0] + " > " + RSILow[1] + " " + BarLow[0] + " > " + BarLow[1]);

Many thanks NinjaTrader_Jesse for your reply.

The prints are showing that all Value[1] are turned to zero (see attached file).

I am using the Series to save the values, but why are these Series saving only the Value[0]?

Thanks!

Hello Stanfillirenfro,

Did you add dashes to the print or modify it? I am unsure how to read this as printed.

I have added dashes to the print to.

Hello Stanfillirenfro,

Can you provide a copy of the updated code showing the print as you added it so I can compare that to the output?

[Stanfillirenfro]

Hello NinjaTrader_Jesse and many thanks for your reply.

Below is the update of the code:

myRSI[0] = RSI(Close, Amplitude, 3)[0];

if(myRSI[0] < Oversold)
{
   RSILow[0] = MIN(myRSI, barBackwards)[0];
   BarLow[0] = MIN(Low, barBackwards)[0];

   Print(RSILow[0] + " > " + RSILow[1] + "--------" + BarLow[0] + " > " + BarLow[1] + "--------" + " : " + Time[0]);
}​

Thanks!

Hello Stanfillirenfro,

If the myRSI[0] value is greater than oversold that condition wont be true for some bars meaning the plot value is not set for every bar. I would suggest adding a print outside that condition so you can see how often that condition is true in contrast to when it is not. If the plot is not set for 2 bars in a row the previous bar value will be 0.

Many thanks NinjaTrader_Jesse for your reply.

Lookig back at the post#1, my probelm is located on the line (a) of the code.
below is the pat of the code with the problem:

if(RSILow[0] > RSILow[1] && BarLow[0] > BarLow[1]) // (a)
{
    Print("Product" + " Size " + ": " + 1000*2 + " : " + Time[0]);
}​

FIRST CASE:
I comment or remove the part of code with BarLow on the line (a) and I have the following modification:

if(RSILow[0] > RSILow[1]) // (a)
{
     Print("Product" + " Size " + ": " + 1000*2 + " : " + Time[0]);
}​

RESULT: On the output window, I have 2000 from the top to the bottom of the window.
CONCLUSION. RSILow is not the problem!

SECOND CASE:

I add the part of the code with BarLow to have:

if(RSILow[0] > RSILow[1] && BarLow[0] > BarLow[1]) // (a)
{
    Print("Product" + " Size " + ": " + 1000*2 + " : " + Time[0]);
}​

RRESULT: There is nothing on the output window, so that I am suspecting the Series BarLow to be causing the problem.

THIRD CASE: I remove the Series RSILow from the code to have:

if(BarLow[0] > BarLow[1]) // (a)
{
   Print("Product" + " Size " + ": " + 1000*2 + " : " + Time[0]);
}​

RESULT: Nothing on the output window.
CONCLUSION: The Series BarLow is the problem.

I am just not understanding why! I am just failing to combine RSILow and BarLow in the same condition.

RSI is plotted on another panel than the chart. Could that be the problem? If yes, is there a line to ba added somewhere to prevent the proplem?

Thanks!

Hello Stanfillirenfro,

It was clear from your previous comment that adding the additional condition caused the overall condition to be false. To know why that is you need to explore how the series is being set before that point. Did you try printing the value on every bar rather than inside the condition? If you are not setting a value on every bar the 1 bars ago value will be not set and invalid which will print as 0.

The panel is not a problem,the RSI is being called in code so that part is irrelevant.

Hello NinjaTrader_Jesse and thanks for your reply.

I have printed the values outside of the condition and they are different from zero on each bar as shwon on the attached file.

Thanks!

[NinjaTrader_Jesse]

Hello Stanfillirenfro,

Please try the print you originally had which was showing 0's in that use case. The print should happen for every bar and then we can check all 4 values being used. For the condition to work you need to have a value set on every bar, if you see output where some 0's are showing up we could explore that further if you provide an updated sample. If a value is being set on every bar you should see that all 4 values are always populated.

Print(RSILow[0] + " > " + RSILow[1] + "--------" + BarLow[0] + " > " + BarLow[1] + "--------" + " : " + Time[0]);

Hello NinjaTrader_Jesse and many thanks for your reply.

The prints outside of the condition are as expected due to the amplitude used, as shown on the attached file.

How to get the correct values in the condition?


Thanks!
