You could do this with a Signal Marker. The syntax of the signal would be...

POS >= 5 AND SUM(CL - SESST > 100 * TINC, 5) = 5

POS would be setup as "Bars from Start of Session" and SESST would be setup as "Highest Price > Open > First 1 Bar of Session".  You would then send to your chart as a Signal Marker and within the Signal Marker preferences, choose the Action you want such as playing a sound.  In the syntax above, I've assumed you are looking for 100 tick increments and not $100 but if the latter, just remove the * TINC.

And to make it a little more restrictive and more likely to only catch that first move to that point...

POS >= 5 AND SUM(CL - SESST > 100 * TINC, 5) = 5 AND CL.5 - SESST.5 <= 100 * TINC

You could always replace the 100 ticks with a C# like C#1...and use a button to adjust this value...

POS >= 5 AND SUM(CL - SESST > C#1 * TINC, 5) = 5 AND CL.5 - SESST.5 <= C#1 * TINC

You could even make the 5 a varaible (C#2) and use a button to adjust it....

POS >= C#2 AND SUM(CL - SESST > C#1 * TINC, C#2) = C#2 AND REF(CL - SESST, C#2) <= C#1 * TINC

Session Stastics is a great solution for all three of these prices you are trying to access.

Open 3 days ago...

High of Last 3 Days...

Low of Last 3 Days...

You would create a signal or custom indicator using tokens like SESST_OP, SESST_HI, and SESST_LO and set the 3 up according to preferences above.
