The CRTLAB Hub
Markets, strategies, free tools, guides, the community board and support, all in one place. Open it from the logo on your chart.
Support chat
Message us from inside the app and get the reply in the same chat.
Write your own indicators
Script an indicator, run it safely in your browser and replay it candle by candle like a built-in.
News on the chart
Economic events are tagged on the candles they moved, so you backtest with the news instead of around it.
US stocks
NVIDIA, Tesla, Apple and more, replayed alongside indices, forex, gold and crypto.
Fibonacci and drawdown calculators
Two new free tools: ICT and OTE Fibonacci levels, and how far you need to climb back from a drawdown.
