#58 The demo soak, looked back on: 13 to 21 October 2026

Demo and testnet accounts only: no real money. Every figure is a share, a ratio or a count.
Last checked: 22 October 2026.

Where the idea comes from

The question

  1. Over the soak, did each account win or lose, and by how much?
  2. How much of that was the bots, and how much the coins that just sat in the wallet?
  3. What was the worst fall on the way?
  4. The demo account jumped 4 to 11% within two minutes, many times. Why?

How we tested

The maths, step by step

1. An account's result. Equity at the end over equity at the start, minus 1. From 100 to 103 is +3%.

2. The held part. An account of 1,000 holds 1 idle BTC that goes from 100 to 110: the held part is +10, or +1%. If the account ended at 1,030, the bots' part is the other +20, or +2%.

3. A bot marked to market. Add up the cash its fills paid and took, then add what its open position is worth at the end and take off what it was worth at the start. Buy 2 at 100, still holding at 105: −200 + 210 − 0 = +10. Then take off its fees and add its funding.

4. A position's step. A long of 20 coins on an account of 1,000, when the coin moves 0.5%: 20 × 0.5% of the coin's price. At a price of 100, that is 10, or 1% of the account. At 20 times the account's equity in positions, a 0.5% move in the coin moves the account 10%.

What we found

1. Four accounts ended up and one down; the market went nowhere.

Percent from each account's start; demo swung 40% down and back on its stress-test positions.

2. Demo's +40% was two leveraged stress-test positions, not the grids.

Each bot marked to market from its own fills, fees and funding; two stress-test legs carry it.

3. Demo's sudden steps were its positions, marked to market.

4. Carry lost on costs and its own trading; tilt and slow mostly followed their coins.

Held coins: the idle coins at the start times their price change; bots: the rest.
