Scalping

Scalping occupied the shortest end of the active trading spectrum. A scalper aimed to capture price moves measured in ticks — the smallest possible price increment — by entering and exiting positions within seconds to minutes. The strategy compensated for small per-trade profits through high frequency: a disciplined scalper might execute fifty to two hundred trades in a single session, targeting consistent small gains while limiting each individual loss to a similarly small amount. The cumulative result, if the win rate and reward-to-risk ratio were favourable, was a steady intraday income stream that was relatively uncorrelated with broader market direction.

In Indian markets, scalping was most commonly practised on Nifty 50 and Bank Nifty futures and options — the most liquid instruments on NSE, where tight bid-ask spreads and deep order books allowed rapid entry and exit with minimal slippage. The Bank Nifty index, with its historically higher intraday volatility relative to Nifty 50, attracted scalpers seeking larger tick movements within the same time windows. Scalpers on Bank Nifty futures typically targeted two-to-five-point moves in the contract, which translated to Rs 100–250 per lot profit or loss given the Bank Nifty futures lot size.

Transaction costs were a critical variable for scalpers, since the cumulative impact of brokerage, STT, exchange transaction charges, and GST could erode or eliminate thin per-trade margins. The emergence of flat-fee discount brokers — most prominently Zerodha, which charged Rs 20 per executed order regardless of size — fundamentally altered the economics of high-frequency intraday strategies for retail participants. Before flat-fee broking became widespread, percentage-of-turnover brokerage structures made scalping economically unviable for small retail traders.

Discipline in stop-loss management was the distinguishing characteristic of profitable scalpers versus unprofitable ones. Because the target profit per trade was small, allowing a single loss to run far beyond the planned stop could erase the gains from multiple winning trades. Experienced scalpers typically defined maximum intraday loss limits — commonly two to three percent of their trading capital — beyond which they stopped trading for the session entirely, regardless of market conditions or the psychological impulse to 'make it back.'

The psychological demands of scalping were significant. The need to make rapid decisions, manage losses without hesitation, and maintain concentration through dozens of trades was taxing. Many participants who attempted scalping discovered that emotional discipline was harder to maintain than technical skill, leading to the common observation among trading educators that while scalping was conceptually simple, it was among the most psychologically demanding execution styles in active trading.
