One trade, start to finish, with every number written down before the order goes in. The trade itself is unremarkable on purpose — the point is the sequence, which is the same whether the account is $500 or $500,000.
A plan written after entry is a story. Written before, it is the only thing that tells you later whether the trade was bad or merely unlucky — and those need opposite responses.
Five lines, before anything is clicked:
Good to know
Line 3 is the one people skip, and it is the one the position size comes out of. If you cannot say where the idea stops being true, there is no trade yet — only an opinion.
Position size is not a decision. It is the output of the three numbers already written down.
What each variable means:
$10 / (35 x $10) = 0.0285 lots, which rounds down to 0.02.
Note
Down, never up. Rounding up to 0.03 would risk $10.50 against a $10 budget. Rounding down to 0.02 risks $7 — under target, which is the direction a rounding error is allowed to go.
The whole trade, before it is placed:
| Pair and direction | EUR/USD, long |
| Entry | 1.0800 |
| Stop | 1.0765 (35 pips) |
| Target | 1.0865 (65 pips) |
| Position size | 0.02 lots |
| Risk if stopped | $7.00 |
| Gain if target hit | $13.00 |
| Margin tied up at 1:100 | $21.60 |
Note the last line. The position ties up $21.60 of a $1,000 account — about 2%. An account that needs most of its balance as margin is holding a position too large for it, whatever the leverage allows.
Try it now
Both numbers come straight out of the calculators: the lot size from the risk and the stop, the pip value from the pair and the size.
Now, and only now, the platform. The order ticket needs the numbers that are already written down, which is the point of writing them down.
Caution
Do not open the position and then decide where the stop goes. That is the order in which accounts are lost — the level that felt obvious beforehand becomes negotiable the moment money is moving against you.
The position opens slightly down, by the spread. On 0.02 lots with a 1-pip spread that is $0.20. Nothing has gone wrong.
Then it sits there. Most of a trade is waiting, and the plan has already answered the two questions worth asking while you wait — where it is wrong, and where it is right.
The trade ends one of three ways: the stop, the target, or you closing it because something in the reasoning changed. The third is legitimate, but it needs a reason you would have accepted beforehand — not discomfort.
Suppose the target is reached at 1.0865. That is 65 pips at $0.20 a pip on 0.02 lots: $13.00, less about $0.20 of spread.
Then record it, while you still remember the reasoning:
| Field | This trade |
|---|---|
| Date | The date |
| Pair and direction | EUR/USD long |
| Reason for entry | Third hold of 1.0780 |
| Entry, stop, target | 1.0800 / 1.0765 / 1.0865 |
| Size and planned risk | 0.02 lots, $7 |
| Outcome | Target, +$13.00 |
| In R | +1.86R |
| Did I follow the plan? | Yes |
That last line is worth more than the profit. A winning trade taken outside the plan is a problem being rewarded, and it will be repeated. A losing trade taken inside the plan is a cost of doing business, and it should be.
R is the trade's result divided by what was risked: $13.00 over $7.00 is 1.86R. Recording results in R rather than dollars makes trades comparable across position sizes and pairs, and it is the unit Track 5 uses throughout.
