reset values when study indicator changes

[oldseller1848]

programing a strategy using a custom study that trades 24 hours/day, I need to reset values when a study is updated.

protected override void OnBarUpdate()
If I add the reset value, it will only reset the value once in this section.

I am able to reset values when orders are executed by using this:
protected override void OnExecution(IExecution execution)

How can I have variables reset when my study changes values?

Hi oldseller1848, unfortunately there's no readymade method for 'when a study changes' - I believe you could check if the calculated values now if different from the last calculated one and then you could reset variables as needed.

Can you post an example of code I can try to use?

You just need to check your study's value and determine if it has changed or not from its previous state.

[1] indexes usually mean previous bar's value. [0] means current bar's value. If [1] != [0] then something has changed.

if (SMA(20)[1] != SMA(20)[0])
{
     // Do something;
}

I need the values to reset immediately after the Study values change. After the values are reset, I need to have this strategy ready to put on more trades if the strategy changes the goShort = True later in the code. This code adjusts the value only once, then it appears not to execute. Is there a different execution method I should use?

 protected override void OnBarUpdate()
        {
            // Reset Data
            if (fibJPYv5.GoShort[0] != goShortLast1)
            {
                goShortLast1 = fibJPYv5.GoShort[0];
                goShort = false;
                goShort1 = false;
                goShort2 = false;
            }
           // GoShort
           if(goShort == true && fibJPYv5.GoShort[0] <= GetCurrentBid())
           {
                //Do more work
           }
        }

This isn't the entire code... I have 3 levels to go short at, depending where the price is with my signal.

You could do this with the code sample Josh provided, just be sure to let the strategy run to update on each tick (CalculateOnBarClose = false).
