The best trading journal for TradingView is RizeTrade, with TradesViz and Tradervue as strong alternatives that pair charting context with execution data. TradingView is among the supported platforms in major trading journals like TradesViz.
Since TradingView itself is a charting platform rather than a broker, you import trades through your connected broker (Tradovate, Interactive Brokers, OANDA) and attach TradingView screenshots to each entry. RizeTrade has built in TradingView Charting so you can review your trades and see exactly how they looked when trading.
