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.
