Drawn on real prices.
Supertrend, HalfTrend and AlphaTrend are part of the 112 indicators, not plugins, and each study draws its own signals.
Supertrend
An ATR band that flips colour where the trend turns.
LT daily, period 10, multiplier 3
HalfTrend
A trend line inside its ATR channel, with buy and sell signals.
MARUTI daily, amplitude 2
AlphaTrend
The trend line and its lag, shaded between, with crossover signals.
SUNPHARMA dailyTrade it. Replay it.
Script it.
Every picture below is the library itself, drawing real NSE prices.
Orders you can see and drag.
Order, stop and target lines sit on the price they belong to. Drag one to modify it, and watch the position line carry its live P&L.
- Tick size, price band and freeze quantity are checked before an order leaves the chart.
- Everything starts in analyzer mode, the sandbox, until you choose live.
- The chart only proposes an order: your broker adapter is the one that sends it.
Replay a session, one minute at a time.
Step or play through past sessions and watch each candle form from real one-minute bars, the way it did live.
- The open never moves, the high and low never pass the real candle’s, and the last step lands on the real close.
- Where the source kept no finer history, the candle forms along a path through its own prices, and the replay bar says Simulated.
- Indicators, drawings and alerts replay with the chart.
Write a study once.
Plot it, backtest it, trade it.
OpenScript is an open trading language that runs on this chart. It compiles in the browser with no eval, a compiled program is plain data, and the same program runs on the TypeScript engine in the page and the Python engine on a server. A runaway script stops at its instruction, memory and time budgets.
