How to use the stake management software?

In case you do not have a ready-to-use betting history, below is a sample file that you can download.

This file has two roles: you can try this staking simulator right away and also use it as a guide on how to build yours.

Simple, yet Important steps to make sure your database is built properly:

• Column 1 is for the result of your bets: value is 1 if your bet was Winner; value is 0 if you lost the bet.
• Column 2 holds the odds for that specific outcome in a decimal format (European. Example: 1.85). I’m planning to implement a code for other formats too.
• Row 1 is for headers. Otherwise, the simulator will skip your first bet.
• The data outside column 1 and column 2 is not essential.

Example:

A staking simulator in sports betting is a tool/software that is capable of calculating and visualizing the profitability of a money management strategy.

A money management simulator specialized in sports betting has the main role of helping bettors in decision-making and optimizing a strategy.

A staking simulator can significantly increase the chance of being profitable with a betting strategy. This process is achieved by excluding certain odds ranges and having the right amount of stake sizing.

The money management simulator analyzes your betting history and displays how your long-term profitability would change.

This simulator also visualizes big swings in profitability. This feature itself can help bettors fine-tune staking strategies.

While using the staking simulator, you can change the stake sizing so you get an instant visualization of how big is the risk of losing the whole betting balance.

What are Max Drawdown and Sharpe-style ratio in staking simulations?

What it is:
The largest peak-to-trough percentage drop in your equity/balance curve. It answers: “What was the worst percentage fall from any high watermark to the next low before a new high?”

How we compute it (your code):

• We walk through the balance series, track the running peak, and for each point compute drawdown = (balance - peak) / peak (a negative fraction).
• We keep the most negative value; that’s the max drawdown.
• In the UI we show it as a positive % via Math.abs(...).

Why it matters:
It’s a risk-of-ruin / pain metric. Two strategies with the same ROI can feel very different if one has a -30% MDD and the other -8%.

Tiny example:
Balances: 1000 → 1050 → 990 → 1040 → 980 → 1000

• Peak is 1050; the worst trough after that is 980 → drawdown = (980 - 1050) / 1050 ≈ -6.67%.
  So Max Drawdown ≈ 6.67%.

Sharpe-style ratio (per bet)

What it is:
Risk-adjusted performance: average return per bet divided by the volatility (stdev) of returns per bet. Higher is better; 0 means no edge after volatility; negative means you’re losing on a risk-adjusted basis.

How we compute it (your code):

1. Convert balances to per-bet returns:
   ri=Bi−Bi−1Bi−1r_i = \frac{B_i – B_{i-1}}{B_{i-1}}ri​=Bi−1​Bi​−Bi−1​​
2. Compute the mean of rir_iri​ and the sample standard deviation of rir_iri​.
3. Sharpe-style =mean(r)stdev(r)= \frac{\text{mean}(r)}{\text{stdev}(r)}=stdev(r)mean(r)​.
   • We treat the risk-free rate as 0 and do not annualize (so it’s per-bet, not per year).
   • If stdev is 0 (no variability), we show “N/A”.

How to read it:

• > 1.0: solid risk-adjusted edge per bet
• ~0.5: weak edge
• < 0: negative edge
  (These are rough, sample-size-dependent heuristics.)

Tiny example (same balances as above):
Per-bet returns ≈ [+5.00%, −5.71%, +5.05%, −5.77%, +2.04%]
Mean ≈ 0.12%, Stdev ≈ 5.49% → Sharpe-style ≈ 0.022 (very small).

Quick notes

• Path-dependence: With percentage staking, MDD depends on the order of wins/losses.
• Sample size: Both metrics stabilize with more bets; short histories can be noisy.
• Scaling: If you ever want a per-100-bets or annualized Sharpe, we can scale by N\sqrt{N}N

What is a staking simulator software in sports betting?

A staking simulator software is an algorithm that is capable of analyzing a sports betting history. It also can calculate and visualize the profitability of a betting strategy.

A staking simulator is based on mathematics and data. With the right type of betting history, a bettor can easily find out which stake sizing approach would result in the most profits.

It’s important to mention that staking software will display data and guides based on historical data. Bettors should not assume that this staking method will have the same result with future bets.

A staking simulator helps you understand your previous staking mistakes, but it can’t guarantee future profitability.

Money management software in sports betting has the main role of optimizing your strategy and reducing unnecessary risks.

Percentage-based betting staking calculator

This sports betting calculator uses one of the most optimized ways a bettor can choose the stakes for each bet.

The simulator’s first field asks you to insert your starting capital. This will be used as if it is a starting balance on your betting account.

With the second setting, you can set up the percentage you want to use for each bet in the following simulation.

When you are done, hit calculate, and the software will apply your staking strategy to the database you uploaded.

By changing the % you are willing to risk on each bet, the tool shows you the possible profits you could earn and a graph that illustrates how the balance would change after each bet.

!Important to notice: for each new row (bet) the software uses the actual/updated balance, not the starting balance. So, if there is a lost bet, the loss is subtracted from the balance.

If the bet was a winner (with a value of 1 in the first column of the Excel), the profits are added to the balance, and the next stake is calculated based on that.

ROI analyzer for odds ranges

This simple tool allows you to analyze the ROI (return on investment) of certain odds ranges.

Example: if you want to find out if you were profitable on odds between 1.40 and 2.01, you just insert these values and hit the check ROI button.

A similar simple Excel rule helped me notice certain odds ranges that were barely profitable or even generated a loss.

These calculations and analyses can significantly increase your profitability and reduce the time you waste by focusing on them.

Flat staking strategy simulator & ROI checker

Similarly to the tool above, this calculator also checks the profitability, and ROI of certain odds ranges.

What comes as an additional feature, is the ability to check the profitability of your betting history if you would use a flat stake for each bet.

A flat stake means using the same stake for every bet, no matter if the previous bets were winners or not.

Martingale staking software

The Martingale staking simulator is based on the basic rule that every time you lose a bet, the stakes on the next bet are doubled.

If you face a longer losing streak, the stakes are doubled until you have a winning bet. After a winning bet, you return to the starting stake.

As you will notice from the simulation above, even a winning strategy can lead to massive losses when using this staking plan.

The main goal of testing this money management strategy is to prove the weaknesses and the major risk of losing the whole betting balance.

By lowering the starting stake to the minimum, bettors can escape a longer losing streak without losing everything.

Reverse Martingale: Paroli System Staking Simulator

The Paroli System is the complete reverse of the above-mentioned Martingale strategy. In theory, it has the role of maximizing profitability when facing a winning streak.

The main idea behind this system is to double the stakes every time after winning a bet and return to the starting stake after a losing bet.

It has a greater advantage when the odds are above 2 (decimal). As you can see from the simulation, in most cases it will result in slow but almost guaranteed losses due to having huge losses because of the doubled stakes.
