Biocon earnings are on tomorrow. Renko Daily & 4hr Added an up Brick (green). this could indicate that the big players are set to send the price up.
Renko going up on before news (earnings) and an event (expiry) despite the sight increase in ATR 14 is often an indication that the big guys know something positive about Biocon.
Observe but trade only if convinced. Set a tight SL if you go for it at opening.
Trade closed: target reached

Bought yesterday @654 (futures price) closed @664. 10 points profit. Nice way to start the morning. This Renko analysis is quite reliable.
