A reverse progression concept that increases only after wins and resets after a loss.

Stake sizing framework

How the strategy works

This is a staking progression, not an entry signal or a method for predicting price direction.

Paroli is a reverse progression concept. Instead of increasing after a loss, it increases only after a win and resets after a loss. That reduces loss-chasing pressure, but gains can be handed back quickly if the planned streak is extended.

01

Step 1

Paroli is a reverse progression: increase only after wins and reset after a loss. It avoids loss chasing, but it can still give back gains if the sequence is extended without a stop.

02

Step 2

Common variants use two-win or three-win cycles, while Half-Paroli reduces the increase at each step. A loss during the cycle returns the next position to the base unit.

03

Step 3

Before testing, confirm that stake, payout, and the previous result remain visible enough to prevent sequence errors.

Worked example

Use the example only as a planning model. It is not a market-direction recommendation, trade instruction, or profit claim.

Demo testing checklist

The broker should show stake changes, payout, order confirmation, and previous results clearly enough to review a two-win or three-win cycle without confusing the sequence.

Use a paper worksheet or demo account to review the full stake path, payout, reset behavior, and cap breach. Do not treat the result as a threshold for funded trading.

Market and expiry context

When the method can be observed—and when to stop

Market conditions and expiry must be written before a demo observation. They are test controls, not claims that a setup predicts direction.

Observe

Market conditions

Paroli does not create consecutive wins; use a single documented demo setup and stable contract terms only to study how a predefined win sequence changes exposure.

Skip

Do not test when

Skip the exercise when payout, asset, expiry, or setup changes between steps, and end the cycle immediately when the planned maximum step or one loss is reached.

Duration

Why expiry matters

Keep one expiry throughout the paper or demo cycle so sequence results are not confounded by different horizons. A shorter duration merely accelerates the cycle and does not increase the probability of a streak.

Definitions used here

Key terms for this page

Open a definition when a broker uses the same label differently or leaves a condition unclear.

01

Payout rate

The percentage return displayed for a contract before confirmation, subject to product and account conditions.

02

Expected value

The probability-weighted average net result under stated win, loss, refund, and payout assumptions. A high payout alone does not establish positive expected value.

03

Loss limit

A voluntary or platform-enforced cap on losses over a session, day, week, or other period. Check how it is calculated and changed.

04

Trade history

A record of submitted contracts, entry prices, expiry times, settlement prices, payouts, and results.

Calculated example

Work through the assumptions

Input

Base stake 1 unit; 80% payout; reinvest stake plus profit after each win

Math

Win 1: +0.8, next stake 1.8. Win 2: +1.44, next stake 3.24. If step 3 loses: 0.8 + 1.44 - 3.24

Result

Net cycle result = -1 unit

Study protocol

What to model before testing

Paroli increases only after a win and resets after a loss. The key test is how much earlier profit is exposed on the final planned step, not whether a short win streak looks attractive.

01

Record 1

Predefined two-step or three-step cycle

02

Record 2

Reset point after one loss

03

Record 3

Profit retained if the final planned step loses

Review metrics

Measure the process, not the story

Confirm that the product is available for the intended user and that the exact operating entity and domain can be verified before any demo study. Define net payout b, assumed win probability p, and full-loss result -1 explicitly. The simple expected value per unit is b × p - (1 - p), and break-even is 1 / (1 + b).

01

Terminal path table

Publish the result for loss at step one, two, or three and for a completed win sequence using the actual payout.

02

Maximum exposed profit

Measure how much earlier cycle profit is placed at risk on the final planned step.

03

Cycle extension rate

Count every case where the prewritten two-step or three-step sequence was extended after seeing a win.

04

Reset integrity

Record losses, ties, refunds, rejected orders, and missed steps separately so the reset rule remains auditable.

How to interpret the worksheet

With full reinvestment and 80% payout, the terminal paths are L = -1, WL = -1, WWL = -1, and WWW = +4.832 units. The attractive completed path must be shown beside the more common early termination paths and a flat-stake comparison.

Sample

Publish the full denominator

Report planned, eligible, skipped, rejected, accepted, settled, missing, and excluded observations. Give every exclusion a reason fixed before its outcome was known.

Timing

Preserve the event chain

Use one timezone and keep submission, acceptance, entry reference, expiry, settlement, and screenshot times when the study depends on execution or duration.

Economics

Use actual payout and cash results

Show the payout distribution, full-loss or refund treatment, fees, stake path, cumulative exposure, and the same result path at a flat stake.

Uncertainty

Separate description from validation

Report missing data, rule changes, median and P95 where timing is measured, and confidence intervals for rates. A small demo batch does not establish an edge or a live-fund threshold.

Platform requirements

What this strategy needs from a broker

Paroli review depends on sequence clarity: the platform should make stake changes, payout, prior result, and reset point obvious enough to avoid extending a planned cycle.

Check that the platform clearly shows the required contract, expiry, payout, order controls, and demo history before testing the method.

Failure conditions

Do not extend the sequence beyond its planned final step. A limited win-streak plan becomes uncontrolled risk when the user keeps increasing the amount after the cycle should end.
