Layering
Layering is a form of spoofing where a manipulator places multiple orders at several price levels on one side of the book to create false depth and pressure, intending to cancel them once the price moves.
By stacking layered orders, a manipulator makes one side of the book look heavy, nudging other participants and algos to trade in the desired direction, then pulls the orders after profiting on the opposite side. Like spoofing, layering is prohibited under SEBI's anti-manipulation rules.
Indian exchanges' surveillance flags patterns of large, quickly cancelled multi-level orders, especially when combined with offsetting executions on the other side. Layering distorts genuine order book imbalance signals that honest traders and algos rely on, which is why it is policed alongside quote stuffing.
