Trading, structure and order flow

Position size

How many units you can open without exceeding the risk you decided on.

%

Usually between 0.5% and 2%.

Structure sets it, not what you would like to risk.

What ONE unit gains or loses if price moves one point.

No currency on purpose: everything is in units of whatever money you use. That way the sum holds in any account and any country.

What it is for

To decide how many contracts or shares you open based on what you are willing to lose, instead of the other way round. It is the only one of these five you use BEFORE every trade, not once a month.

How to use it

  1. 1Enter your account capital and what percentage you accept losing if the trade fails.
  2. 2Measure the distance to the stop in points. The chart structure fixes it: the level that would invalidate your idea.
  3. 3Enter what one point is worth on the instrument you trade. It is a contract spec, not an estimate.

How to read it

The unit count is a ceiling, not a target. It always rounds down: with 2.9 contracts you open 2, because opening 3 exceeds the risk you just set.

If it returns zero, the answer is not "I will open one anyway". That stop does not fit that account: either the stop is shorter —and then it was a different idea— or the instrument is too big for your capital.

Real risk almost never matches what you asked for, because units are whole. Look at that number, not the theoretical one: it is what you will lose.
