When it takes effect

NinjaTrader: sent to the add-on right away, or when it next connects. Tradovate: within about 10 seconds.

Notes

• Restart also turns blockSignals and closingOnly off, unless switchesLocked is on.
• On NinjaTrader, restart is refused with 409 would_retrip when the current P&L is already at or past the daily target or limit. Change the limit first.
• Restart costs 2 units of your change budget.
