# 100-Trade Sample Analysis: What the Numbers Tell You

A 100-trade sample is the minimum meaningful dataset for most trading strategies. Here is how to analyze it properly.

## Why 100 Trades

Fewer than 100 trades: a single hot or cold streak can dominate your numbers.
100 trades: fluctuations start to average out and patterns emerge.
300+ trades: high confidence in the statistics.

## The Core Metrics to Calculate

From your 100 trades, calculate:

**Win rate** = Winning trades / 100

**Average win** (in R or $) = Sum of winning trades / number of wins

**Average loss** (in R or $) = Sum of losing trades / number of losses

**Profit factor** = (Win rate × average win) / (Loss rate × average loss)
- Below 1.0: losing strategy
- 1.0–1.3: marginal edge
- 1.3–1.7: solid edge
- Above 1.7: strong edge

**Expected value per trade** = (Win rate × avg win) − (Loss rate × avg loss)
This is how much you expect to make per trade on average.

**Maximum consecutive losses** = longest losing run
This tells you what drawdown to emotionally and financially prepare for.

## Breaking Down the 100 Trades

Do not stop at overall stats. Segment the 100 trades:

**By setup type:** Which tags had the highest profit factor?
**By session:** London vs New York vs Asian performance
**By day of week:** Is Friday trading dragging down your overall numbers?
**By pair:** Are 90% of your profits coming from one pair?
**By month:** Are two bad weeks skewing the entire sample?

## Red Flags in a 100-Trade Sample

**One or two trades represent 50%+ of total profit:** Lucky outliers, not repeatable edge.
**Win rate below 35% with R:R below 2:** Mathematically difficult to be profitable.
**Profit factor varies wildly by week:** Strategy may not have consistent edge.
**Losing trades 2x larger than planned:** Risk management is breaking down.

## What to Do With the Results

If profit factor > 1.3: continue trading the strategy, scale up gradually.
If profit factor 1.0–1.3: isolate your top-performing setups and trade only those.
If profit factor < 1.0: do not go live with this. Return to backtesting.

## Summary

100 trades gives you numbers. Those numbers tell you whether you have a strategy or a hope. Run this analysis every time you reach the next 100-trade milestone — strategy performance can shift, and regular analysis keeps you aware.
