Subject: [PATCH] =?UTF-8?q?Add=20Random=20direction=20option=20=E2=80=94?=
 =?UTF-8?q?=20picks=20Buy=20or=20Sell=20once=20per=20batch?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

All accounts in the same batch trade the same resolved direction.
Each new batch (after positions are flat) picks a fresh random direction.
