THE DUBAN FIELD GUIDE

Bet with a plan.
Stay in the game.

A foundational guide for every bankroll — from a single small-stake accumulator to a high-capacity betting portfolio.

RULE 00Your bankroll is money you can lose completely.

It is not rent, savings, emergency money, debt, or tomorrow's deposit.

01 / FIND YOUR LANE

Bankroll changes the constraints.
It does not change the mathematics.

Choose the row containing your dedicated betting bankroll. If your discipline or record-keeping belongs to an earlier tier, use the earlier tier.

01$1–$49

Small-stake & acca

Entertainment first

At this size, percentage staking is often smaller than a bookmaker minimum. Treat every stake as the full cost of the entertainment, not the first step in a recovery plan.

UNIT GUIDEA fixed $1 ceilingEXPOSUREOne planned bet or acca

Build this

Decide the total before opening the app.
Prefer singles when the aim is to learn.
If you build an acca, keep it to one fixed stake.

Avoid this

Reloading after a loss
Adding legs just to enlarge the payout
Calling a longshot a bankroll strategy

02$50–$249

Learning bankroll

Build a repeatable process

Your first target is a clean record, not income. Use the same unit, log the price you took, and gather enough decisions to separate a sound process from a lucky week.

UNIT GUIDE0.5–1% or fixed $1EXPOSUREUp to 3 units per day

Build this

Track singles, price, result and closing line.
Review in blocks of at least 50 decisions.
Keep one bankroll for all active bets.

Avoid this

Changing unit after every result
Following a hot streak blindly
Betting because a match is on TV

03$250–$2,499

Structured bettor

Protect the downside

This is large enough for percentage staking to work. Separate selection quality from stake size, line-shop, and measure whether your prices beat the market close.

UNIT GUIDE0.5–1% of bankrollEXPOSURE3% daily exposure guide

Build this

Recalculate the unit after a 10% bankroll move.
Count correlated bets as one larger position.
Use a stop rule when the process breaks down.

Avoid this

Martingale or loss chasing
Treating confidence as certainty
Ignoring the price and betting only the pick

04$2.5k–$24,999

Advanced portfolio

Size only proven edges

More capital does not create more edge. Fractional Kelly can help only when probabilities are calibrated and the offered price is real; otherwise a smaller flat unit is safer.

UNIT GUIDE0.25–0.75% base unitEXPOSURE1.5% single-position cap

Build this

Use multiple books and record the best available price.
Audit calibration, CLV, drawdown and market by market.
Reduce size when liquidity or evidence is thin.

Avoid this

Full Kelly from a small sample
Scaling low-limit props linearly
Confusing turnover with performance

05$25k+

High roller

Liquidity is part of the model

The constraint becomes execution: limits, slippage, account access, correlated exposure and market impact. The right percentage can be lower than it was for a smaller bankroll.

UNIT GUIDEOften below 0.5%EXPOSURESet by market capacity

Build this

Separate strategy capital from living and business capital.
Model execution cost before increasing a position.
Keep tax, legal and counterparty records for your jurisdiction.

Avoid this

Forcing size into a soft market
Using one bookmaker as the source of truth
Assuming status or bankroll improves a forecast

Illustrative limits, not personalised financial advice. Use the lower limit whenever your probability, price, liquidity, or self-control is uncertain.

02 / THE OPERATING SYSTEM

Six rules that survive every tier.

Price before pick

A strong opinion at a bad price is a bad bet. Compare the model probability with the no-vig market probability.

Singles are the baseline

Every accumulator leg compounds the bookmaker margin. Use accas as capped entertainment, never as a recovery tool.

Size from bankroll

Use a small percentage of the current bankroll. Never increase a stake merely because the previous bet lost.

Count correlation

Several bets on the same game or player can fail together. Treat them as one combined exposure.

Grade the process

Record the number taken, model version, result and close. Review CLV, calibration and drawdown — not just wins.

Pause is a position

Stop when limits are broken, money is needed elsewhere, emotions are driving decisions, or the price has disappeared.

03 / RESTRICTED

Make the decision inspectable.

Check the price, write down the stake, and know what would make you pass.
