Sorted by the gap people quote. Read the net column.
In this sample, 8 of 10 rows end below zero and the other 2 are thin. The biggest gap on the board goes furthest under. A board that takes the fees off first is the whole idea.
One row, taken apart: S-01, example
Gross gap+1.18
Buy fee−0.20
Sell fee−0.20
Moving the coin−0.71
Depth, price moves−0.35
Net after fees−0.28
The thin line marks zero. Figures are examples, in percent of a sample trade.
What each column counts
- Gross gap
- Best sell price on one venue against best buy price on the other.
- Fees
- Trading fees on both sides, the cost of moving the coin, and what depth takes at the sample trade size.
- Net after fees
- What remains of the gap. A measurement of a gap, not a suggestion.
One pair over a sample day, example
Amber line: the gap between two venues. Dashed red line: fees on that route, about 0.31 percent. Only what pokes above the dashed line is a gap at all, and only for moments. Example drawing, not market data.
A row as data, example
{
"row": "S-06",
"coin": "COIN A",
"buy_on": "EXCHANGE A",
"sell_on": "EXCHANGE B",
"gross_gap_pct": 0.38,
"fees_pct": 0.34,
"net_after_fees_pct": 0.04,
"example": true,
"live": false
}What a data publisher could build here
- A delayed public board. Gaps with fees already off, free to read.
- A fee table. Every venue's trading and moving costs, kept current, with the date each one was checked.
- A read-only data feed. For researchers and writers who quote these numbers and want them after fees.
What this board will never do
- NOTrade button. You read the board, and that is all it does.
- NOKeys or wallets. It never connects to an exchange or to your account.
- NOMoney. Nothing here holds it, moves it or asks for it.
- NOTips. A row is not a suggestion to buy anything. Not financial advice.
