Beginners often feel they need dozens of indicators. A better starting point is simpler: define one question, measure it with historical data, inspect the result from several angles, and understand the limits of the evidence.
Start with a company or index you understand well enough to know what you are researching.
For example: how has this stock historically behaved during November and December?
Use a recurring date window across many years rather than looking at one recent chart.
Check win rate, average, median, sample size and year-by-year dispersion together.
Historical tendencies can change. Use the result as one input, not as a guarantee.
Try other lookback periods to see whether the conclusion is stable or dependent on one sample.
| Beginner mistake | Better habit |
|---|---|
| Looking for a guaranteed setup | Looking for evidence and uncertainty |
| Using only average return | Also check median and yearly results |
| Ignoring sample size | Count the number of observations |
| Changing dates until a result looks good | Define the hypothesis before testing |
