Understand the narrow objective
Scalping attempts to capture small price changes through very short holding periods. Because the intended gain is small, the distinction between a visible quote and an executable price becomes especially important. Define the instrument, market conditions and exact decision rule. Many frequent trades do not create an advantage by themselves; they also repeat exposure to spreads, execution uncertainty and operational mistakes.
Stress realistic market conditions
Evaluate the strategy with bid and ask information where possible rather than treating the last traded price as both entry and exit. Include queue position, partial fills, rejected orders and the possibility that liquidity disappears. Faster automation cannot remove these issues, and a historical simulation may not capture them. A small change in assumed cost can materially change a high-turnover strategy's result.
Control operational complexity
Short decision intervals can magnify the consequences of a stale feed, connection problem or mistaken order size. A research plan needs explicit stop conditions and a way to reconcile positions after an interruption. The FYLU information site does not supply low-latency execution, a scalping bot or order-routing infrastructure. No speed, profitability or execution-quality commitment is implied by this educational description of the technique.
