DATA & MODEL LIMITS
What sits behind the chart?
This page explains where the chart comes from, what stays hidden, and which mechanics are modeled.
Where does the chart come from?
Crypto charts are built from executed trades on Binance USDT-M perpetual markets. We check the candles we build against Binance's own reference candles; if they don't match, we don't use the data. We never create new prices or artificial moves to make a session more interesting.
Gaps in the data
If the source data has a gap inside a period we would otherwise use, we drop that period entirely. We don't quietly fill it from another source.
Why ^ units?
Prices are shown in ^ units instead of dollars. The reason is simple: the real price level would reveal the period you are looking at.
What stays hidden?
While you trade, you don't see the date or the candles ahead. The price is scaled by a ratio you don't know, so you can't work out the period from the levels either. None of this is left to the browser: the candles ahead are never sent to it, so there is nothing to fast-forward to.
What do we model?
Price movement is not modeled. We model three things: spread, funding, and mark price. Wherever a model is in use, it's labeled on screen — including when we use the last traded price instead of mark price.
What stays on record?
Every session's record opens in Review, and completed sessions accumulate in History. In Solo, the plan you wrote and the discipline signals from the session sit in the same record. Records are not altered afterwards.
When FX arrives
FX will have a different data source and different limits. It will be presented separately, it will not carry the same data claim, and its records will be kept apart from crypto.
Clear limits. The decision is yours.
