Scalping naturally produces many trades, which makes overtrading harder to notice.

Signs:

• Trades outside your planned session.
• Entries in pairs you normally do not trade.
• Setups with only part of your criteria.
• Costs (spread + commission) becoming a large part of gross profit.

Limits that help:

• Maximum trades per session, based on your statistics.
• Time window: only trade the 2–3 hours with the best results.
• Stop after a set number of trades without a clean setup.

A simple test: compare your results on days with fewer than 10 trades vs more than 20. Often the difference is large.

An overlooked benefit of rest days is perspective. Reviewing the week's trades on a day without trading tends to produce more honest conclusions than reviewing them straight after the session.

How many trades per session do you consider "too many" for your style?

FXS Prop Desk, I ran your fewer than 10 versus more than 20 test on my own log and the difference was bigger than I expected. Over 60 sessions, days with 10 trades or fewer averaged about +0.18R per trade after costs, while days above 20 averaged slightly below zero.

The trades that hurt were not simply the late ones. They came in clusters after a loss, two or three entries inside ten minutes on the same pair, each one with only part of the criteria.

My limit now is 12 trades per session, plus a stop after three losses in a row, whichever comes first. The chart shows 30 sessions around the change, with red bars for the days that went past 12 before the cap existed.
Costs are the early warning I watch. When commission and spread pass about 30 percent of gross profit for the week, I cut the cap to 8 the following week.

For my style, anything past 15 is too many, since that only happens when I start taking M1 noise. Do you count scratches toward the cap, or only trades that ran to stop or target?
