Trade Frequency
Trade frequency is how often you trade. Higher frequency multiplies costs and decisions, so it only makes sense if each trade has an edge after those costs.
Trade frequency is simply how often you open new positions. It matters because every trade carries a cost and a decision. More trades only help if each one still has an edge after those costs are paid.

Trade frequency in plain words
Each trade usually costs a commission, so trading more means paying more.1
Fees look small, but over time they add up to a big drag.1
Overconfidence tends to make people trade too much.2
How to set a sensible trade frequency
Count your trades
Log every trade in a Trading Journal and count them per week.
Price each trade
Add commission, Bid-Ask Spread and Slippage to get a cost per trade.
Check the edge
Compare your Expectancy per trade with that cost.
Set a cap
Cap how many trades you can make per day or week.3
Watch your mood
Watch your confidence — heavy trading often goes with overconfidence.4
Review monthly
Change the cap only after reviewing a large sample of trades.
Worked examples
Example 1 — Many small trades
Costs winA hypothetical trader makes 20 trades a week with a small gross edge per trade.
| Gross edge per trade | 0.1R |
| Cost per trade | 0.15R |
Costs ate the profits, so the edge vanished.1
Example 2 — Fewer, better trades
Quality over quantityThe same hypothetical trader cuts to 5 planned setups a week.
| Net edge per trade | 0.3R |
| Weekly result | +1.5R |
Overconfident investors will trade too much; trading less left room for the edge to show.5
Example 3 — Cap reached
Rule keptA hypothetical trader hits a daily cap of 3 trades and stops.
| Daily cap | 3 trades |
| Extra trades taken | 0 |
A daily trade cap kept the plan on track.3
High vs low trade frequency
| Aspect | High frequency | Low frequency |
|---|---|---|
| Costs | Add up fast | Smaller total |
| Decisions | Many, often rushed | Fewer, more planned |
| Edge needed per trade | Must beat costs each time | More room after costs |
| Emotional load | Higher | Lower |
