Is this a subscription?
No. You pay once. Updates are included for a year; after that the version you have keeps working exactly as it did, offline, with no expiry. Renew only if you want the newer builds.
Where does the price data come from?
From you. Export history from the broker you trade with and import it — that way the chart matches your terminal instead of some third party's feed. No market data is bundled, and none is ours to redistribute.
Does it work offline?
Yes. After the first load everything runs locally, including licence checks — the licence is a signed key your browser verifies on its own, not a call to a server.
Does it place trades?
No. It is an analysis and testing tool. It does not connect to a broker, cannot send an order, and never asks for account credentials.
Which markets does it work with?
Any instrument you can export bars for — gold, forex, indices, crypto. Nothing in it is specific to one symbol.
What if my data is a strange format?
Try it — the importer works the format out from the file and shows you what it found before saving anything. Charting is free, so it costs nothing to check.
