What it does
TRDR adds order-book levels, depth overlays and alerts to TradingView-based crypto charts. A free account has restricted indicators and timeframes; paid Pro and Premium plans expand access, with a seven-day Pro trial available in Billing.
Start with a market and decide which exchange’s liquidity you want to inspect. Turn on Aggregation and choose venues for a combined depth view. Order Book Top Levels behaves differently: it requires an individual exchange, so it can disappear when the surrounding depth widget switches to an aggregate.
Top Levels draws the largest price levels on the chart and lets you adjust their number and distance from the best bid or ask. Depth Overlay uses bands around candles to compare the two sides of the book. Select a price level in Changes to inspect additions and removals over a rolling window; the sticky setting follows the highest bid and lowest ask.
These are displayed orders, which can change before execution. TRDR provides analysis rather than direct trading. Its history limit is 10,000 candles for intervals of one minute or longer, and private TradingView indicators cannot be imported.
The website currently shows Pro at €23.95 per month against €29.95, and Premium at €47.95 against €59.95, with the promotional prices marked as expiring after six months. Check the billing screen for the selected term and subsequent charge.
Mobile browsers can open TRDR, but there is no dedicated mobile app and some dragging or scrolling controls are less suited to phones.
