A scalper targeting five pips on EURUSD with a one pip spread is giving up twenty percent of the target before the trade even starts moving. Add a broker commission on top of the spread and the real cost can eat a third of a small target before the market has done anything at all. Scalping is sold as the fast lane to profit because trades resolve in seconds or minutes. What rarely gets said out loud is that the smallest timeframes carry the highest cost-to-target ratio of any style of trading, and that math has to be beaten before skill even enters the conversation.
The arithmetic scalping must overcome
Every trade pays the spread, and often a commission, regardless of outcome. On a strategy targeting 20 pips per trade, a 1 pip spread is a 5 percent cost. On a strategy targeting 5 pips, that same spread is a 20 percent cost, four times more expensive relative to the reward. Scalpers are not just trading a smaller timeframe, they are trading against a much larger relative cost, which means the underlying edge, the actual skill in reading short-term price, has to be considerably sharper just to break even, before it can be profitable at all.
What the job actually demands
Scalping rewards a narrow set of traits: fast, calm execution under real time pressure, the ability to read short-term price action without hesitating, and total focus for a compressed window rather than sustained attention across a full session. It punishes hesitation harder than any other style, since a half second of doubt on a five minute chart is the equivalent of missing an entire session on a daily chart. It also punishes overtrading uniquely hard: because each trade is quick, it is tempting to take far more of them than any account or execution setup can actually support well, and cost erosion compounds with every extra trade taken out of boredom rather than genuine signal.
Who it suits, and who it quietly ruins
Traders with fast reflexes, low latency execution, and the discipline to stop after a defined number of attempts tend to do this work reasonably well. Traders drawn to scalping because it feels active and exciting, without the execution speed or discipline to match, tend to rack up cost from overtrading faster than they build any real edge. Scalping is not a shortcut around the harder skill of reading a chart; if anything it demands a sharper version of that same skill, applied under tighter time constraints and a worse cost structure.
A realistic scalp framework for majors
One workable structure on EURUSD during London hours: wait for price to pull back to a five minute 20 EMA inside an established short-term trend, and enter on a rejection candle that closes back in the trend's direction, with the spread checked before entry and skipped if it is unusually wide. Stop goes a few pips beyond the rejection candle's extreme, typically 6 to 10 pips, because a scalp stop that is too tight simply gets clipped by normal spread and noise. Target sits at the next minor swing point, often 10 to 15 pips away, giving a modest but real reward relative to the risk once costs are accounted for. Invalidation is a close back through the 20 EMA against the trade, which says the short-term trend that justified the scalp is no longer there.
