Default is OFF every day. Send ZERODHA YES (exactly, capitals) to the Telegram bot to switch the mirror ON for the rest of today; it then copies every new entry the Dhan gold algo fills (same option, same lots, LIMIT 40 below the option price, hard stop +600 at Zerodha, Dhan's exits mirrored). Send ZERODHA NO to switch it OFF. It switches OFF by itself at 23:40 IST. OFF only blocks new entries: an open mirrored trade is always managed to its exit.
