Mouse hand, tense shoulders

Scalping is physical in a way that's easy to ignore. Hours of precise clicking, a hand that hovers over the buttons, shoulders that creep up toward the ears during volatile moments.

Repetitive strain builds slowly. A numb patch on the fingers, a sore wrist, an ache between the shoulder blades by the end of the week. Tension also affects clicking accuracy, and a stiff hand clicks the wrong button more often.

An ergonomic setup pays back in precision. A mouse that fits the hand, a chair with proper back support, a desk at the right height so the forearm rests level.

Many scalpers switch to keyboard shortcuts for common actions, which reduces mouse travel and speeds up execution. A hotkey for "buy", "sell", and "close" requires a bit of setup and a demo-account trial, but it cuts both strain and delay.

Short stretches between trades, or at least between sessions, keep tension from building.

The body is part of the trading system. A sore, tense body makes slower and sloppier decisions, and no indicator fixes that.

Which hardware or posture change helped most during long sessions?

For me it was the mouse. I'd been using a small travel mouse for years, and after a few months of long sessions I had a dull ache running up the outside of my forearm. A vertical mouse felt silly for about a week, then the ache was gone within a month. My clicks also got more deliberate, which I hadn't expected.

Hotkeys were the second big change. I mapped buy, sell and flatten to keys on the left side of the keyboard and practised on demo for two weeks before going live. The first few days I hit the wrong one once or twice, which is exactly why the demo period matters. Now my right hand barely moves during a trade.

Posture was the slowest fix. I raised my main monitor so the top edge sits at eye level, because I'd been hunching forward to read the order panel. I also stand up between every trade, even for thirty seconds. It sounds minor, but my shoulders stopped feeling like concrete by mid-afternoon.
