Scalping is a trading style that seeks to profit from small price movements in the forex market. Scalping EAs (expert advisors) are algorithms programmed to automate scalping strategies. They open and close trades within minutes, aiming to capture profits from even tiny market fluctuations.

Scalping EAs are optimized to spot market trends, volatility, and liquidity across small timeframes like the 1 minute or 5 minute charts. They enter high probability trades based on parameters like RSI, moving averages, breakouts, and micro price action. Strict risk management is coded with tight stop losses.

Benefits of scalping EAs include exploiting temporary market inefficiencies, diversification across multiple currency pairs, and avoiding trader emotions/biases. However, spreads, commissions, and latency are risks to weigh. Robust backtesting and optimization are critical.

Overall, scalping EAs allow traders to automate a very short-term trading approach. They can generate profits during volatile market swings intraday. But like any EA, careful development, testing, and monitoring is required to mitigate risks. When coded correctly, scalping EAs provide an advantage through disciplined execution of scalping tactics. But the coded logic needs expertise.
