# Timeframe Agreement Worksheet

*Signal Pilot Education — companion to Lesson 39: Trading More Than One.*

The standard advice is to read three charts and act only when they agree. On the lesson’s sixty bars, three widths of the same tape agree on nine bars in forty and all three call a trend on seven. Whether that exchange is worth making is arithmetic with two break-even points rather than one.

## 1. Measure the agreement rate before you require it

Pick your three widths and one rule that gives each a yes or no. Score **forty
bars** on all three.

| Width | Yes count | Yes rate | No rate |
| --- | --- | --- | --- |
| Narrow | | | |
| Middle | | | |
| Wide | | | |

For each pair, compare observed agreement against what unrelated series would
give:

| Pair | Observed agreement | Independent agreement = (yes×yes) + (no×no) | Observed − independent |
| --- | --- | --- | --- |
| Narrow × middle | | | |
| Narrow × wide | | | |
| Middle × wide | | | |

If observed agreement is not comfortably above the independent figure, **your
third chart is not a second witness** and its confirmation is not evidence.

## 2. Get the two rates your filter actually has

This needs the record of setups you did **not** take, which is the whole reason
to log them. Over your last hundred candidate setups:

| | Filter removed it | Filter let it through | Total |
| --- | --- | --- | --- |
| **Losers** | (a) | (b) | |
| **Winners** | (c) | (d) | |

| | Your number |
| --- | --- |
| **Accuracy** = a ÷ (a + b), the share of losers removed | |
| **Damage** = c ÷ (c + d), the share of winners removed | |

Almost nobody has these numbers and almost everybody has an opinion about the
filter.

## 3. Compute the ratio your filter has to beat

| | Your number |
| --- | --- |
| Sum of every winning trade in your record | |
| Sum of every losing trade | |
| **Profit factor** = the first ÷ the second | |

| Break-even | Condition |
| --- | --- |
| Expectancy per trade rises | accuracy > damage |
| Money rises | accuracy > damage × profit factor |

Compare the ratio against what you measured in part 2. **Almost everything sold
as a filter lives in the gap between those two break-evens**: it improves the
average trade and reduces the total.

If the profit factor comes out below one, the strategy is losing money and
almost any filter helps, which is worth knowing for a different reason.

## What you are holding when this is filled in

Two comparisons and a threshold: whether your extra chart agrees more than unrelated series would, what your filter removes on each side, and the profit factor your accuracy has to exceed your damage by before the filter makes money rather than just a better-looking average.
