Indicators and drawing tools
Open the indicators button on the trading screen and press Add. The library has about a hundred scripts in groups: moving averages, trend (Supertrend, Ichimoku, ADX, Parabolic SAR), momentum (RSI, MACD, Stochastic, Squeeze), volatility and bands, volume, session levels (opening range, initial balance, sessions, kill zones, pivots) and ready made strategies. Search by name, for example "VWAP" or "opening range".
Each one has a settings button with its inputs and a Style tab for colors, line widths and which lines to show. Oscillators get their own panel under the price. A strategy on the chart marks its entries and exits and shows its trade count and result.
Everything in the library is a script you can open and copy into the script editor to change or write your own.
The drawing rail on the left has lines, rays, rectangles, fib retracements, vertical lines and a long or short position tool.
