How risk-based position sizing works

The idea is simple: decide the most you are willing to lose on a trade first, then let your stop -loss set the size. That way a losing trade costs a known, bounded amount instead of whatever the market takes.

The math: risk amount = account × risk %. Risk per unit = the gap between entry and stop-loss. Units = risk amount ÷ risk per unit. Multiply by entry to get the dollar position. A tighter stop means a bigger position for the same risk; a wider stop means a smaller one.

How Sentari sizes trades

Sentari applies the same discipline automatically. When a verdict clears your conviction threshold and you have auto-execution on, it sizes the position from your capital cap and the strength of the verdict — within the limits you set, on your own Kraken account, non-custodial.

Frequently asked questions

What is position sizing?
Position sizing is deciding how much to put into a single trade. The risk-based method ties it to a fixed amount you're willing to lose: you set a risk percent of your account, and your entry and stop-loss determine the largest position that keeps the loss within that limit.
How is position size calculated?
Risk amount = account balance × risk %. Risk per unit = the distance from entry to stop-loss. Position size (in units) = risk amount ÷ risk per unit. Multiply by the entry price to get the position value in dollars.
How much should I risk per trade?
Many traders cap risk at a small fraction of their account per trade so that no single loss is damaging. The right number is personal and depends on your strategy and tolerance. This is a tool, not financial advice.
Does Sentari size positions for me?
Yes. When Sentari auto-executes a verdict on your Kraken account, it sizes the position from your capital cap and the verdict's conviction, within the limits you set. You can also run it in simulation mode first.
