This code works, with the help of Grok... I can assign an ACS hotkey and it will maintain the toggle now as a subgraph Value:
For anyone else interested, just save it in the usual file and run the remote build...




#include "sierrachart.h"

SCDLLName("Toggle Subgraph - Perfect ACS Sync")

SCSFExport scsf_ToggleSubgraphPerfect(SCStudyInterfaceRef sc)
{
SCInputRef ButtonNumberInput = sc.Input[0];
SCSubgraphRef ToggleValue = sc.Subgraph[0];

if (sc.SetDefaults)
{
sc.GraphName = "Toggle Subgraph - Perfect ACS Sync";
sc.StudyDescription = "One-click toggle. Button depressed = 1, released = 0. Perfect sync.";
sc.AutoLoop = 0;

ButtonNumberInput.Name = "ACS Button Number (1-150)";
ButtonNumberInput.SetInt(1);
ButtonNumberInput.SetIntLimits(1, 150);

ToggleValue.Name = "Toggle State";
ToggleValue.DrawStyle = DRAWSTYLE_LINE;
ToggleValue.PrimaryColor = RGB(0,255,0);
ToggleValue.LineWidth = 2;
ToggleValue.DrawZeros = true;

// Required for ACS button events
sc.ReceivePointerEvents = ACS_RECEIVE_POINTER_EVENTS_ALWAYS;

// Initialize button state to off (matches default persistent 0)
int InitialTargetID = ACS_BUTTON_1; // Default to button 1
sc.SetCustomStudyControlBarButtonEnable(InitialTargetID, false);

return;
}

int SelectedBtn = ButtonNumberInput.GetInt();
if (SelectedBtn < 1 || SelectedBtn > 150) SelectedBtn = 1;
int TargetID = ACS_BUTTON_1 + (SelectedBtn - 1);

// === Detect and process ACS button toggle event ===
if ((sc.PointerEventType == SC_ACS_BUTTON_ON || sc.PointerEventType == SC_ACS_BUTTON_OFF) &&
sc.MenuEventID == TargetID)
{
int NewState = (sc.PointerEventType == SC_ACS_BUTTON_ON) ? 1 : 0;
sc.SetPersistentInt(1, NewState);

SCString Msg;
Msg.Format("ACS Button %d → %s", SelectedBtn, NewState ? "ON" : "OFF");
sc.AddMessageToLog(Msg, 1);
}

// === Synchronize button visual state to persistent value ===
int CurrentState = sc.GetPersistentInt(1); // 0 or 1
sc.SetCustomStudyControlBarButtonEnable(TargetID, CurrentState != 0);

// === Output to subgraph ===
for (int i = sc.UpdateStartIndex; i < sc.ArraySize; i++)
ToggleValue = static_cast<float>(CurrentState);
}
