pivotHigh pivotLow on first bar of session

[wisdomspoon]

I feel really silly for not figuring this out, but alas I need some help.

Developing the code for a strategy that trades during the open: 8:30a - 9:30a.

The very first bar that is printed uses the high of that bar as a pivotHigh and the low of that bar as pivotLow. At the end of the trade session every day (9:30a) I'm having the code reset the values of pivotHigh and pivotLow so that we don't go into the next day using any of the previous pivots. I do that with this code within onBarUpdate:

{
// Reset pivot variables after 9:30 AM
if (Time[0].TimeOfDay > new TimeSpan(9, 30, 0))
{
if (!isSessionReset)
{
pivotHigh = 0;
pivotLow = 0;
isSEMDetected = false;
Print("Pivot High and Pivot Low reset");
isSessionReset = true;
}
return;
}
else
{
isSessionReset = false;
}

Then I use instructions to set the pivotHigh and pivotLow to the High and Low of previous bar if current bar is 1.

// Wait for the first bar after 8:30 AM
if (Time[0].TimeOfDay < new TimeSpan(8, 30, 0) || Time[0].TimeOfDay > new TimeSpan(9, 30, 0))
return;

// Set Pivot High and Pivot Low on the first bar
if (CurrentBar == 1)
{
if (pivotHigh == 0 && pivotLow == 0) // Check if not already set
{
pivotHigh = High[0];
pivotLow = Low[0];
Print("Initial Pivot High: " + pivotHigh);
Print("Initial Pivot Low: " + pivotLow);
}

In my print logs I'm seeing that at the end of the previous day, pivotHigh and pivotLow are being reset.
But on the following day, as an example, I see that a short trade is entered (even though conditions haven't been met because the strategy will require at least 2 bars to trade), it is setting the pivotHigh to the correct price (high of the first bar at 8:30a close) but it has not set the pivotLow to the low of the first bar. A short trade is taken (without the conditions being met), and then when the long trade is taken (conditions are met) it does correctly set the new pivotLow. I really need that pivotLow set at the low of the first bar though. I'm using Calculate.OnBarClose

Here are the print logs starting from post session (9:30a+) and the opening session of today:

TL;DR: pivotHigh and pivotLow are not being accurately set based on the price action of the first bar of session. I'm using a private double variable to set pivotHigh and pivotLow:
private double pivotHigh = 0; // Pivot High
private double pivotLow = 0; // Pivot Low

Hoping someone can help.

From the given details all I could recommend would be trying to use the actual session begin proerty IsFirstBarOfSession to ensure that your reset is happening on the first bar of the session. You shouldn't need to reset anything at the end of the session because nothing can happen before the next first bar of the session, your resets should generally be in the first bar of the session condition.

You would otherwise need to add more prints to identify how your logic is working in that use case to make sure its all logically correct.
