NinjaTrader — execution exports (fills) and bar exports — 5-second, 1-minute, 100-tick

TradingView — chart exports (Export chart data…) — 5S, 10S, 15S, 30S and 1-minute

DeepCharts — trade lists (Strategy Report → Trade List → CSV)

Re-importing the same file is always safe — rows are deduplicated. Everything else about the journal: the Guide · FAQ · create a free account.

Your platform isn't on the list? send a sample — the importer gets built from it

Export a trade list / fills report / chart data CSV from your platform (Sierra Chart, Tradovate, Quantower, ATAS, Rithmic, anything) — anonymize account numbers if you like, a few rows are enough. Only the first 200 KB are kept.
