Strategy

The strategy API lets you build and backtest trading strategies with entry/exit signals, stop-loss, and take-profit.

Declaration

strategy('My Strategy', { overlay: true })

• name string — strategy name shown in the legend
• opts { overlay?: boolean } — true to draw signals on the price chart (default: true)

strategy.entry(id, direction, opts?)

Open a new position. If a position in the opposite direction is open, it is closed first.

• id string — position identifier
• direction 'long' | 'short' — trade direction
• opts { sl?: number, tp?: number, label?: string }
  • sl — stop-loss price level
  • tp — take-profit price level
  • label — custom label for the signal marker (defaults to id)

strategy.entry('Long', 'long', { sl: close - ta.atr(14) * 2, tp: close + ta.atr(14) * 3 })

strategy.close(id?)

Close an existing position. If id is provided, only closes the position with that ID.

strategy.close('Long')   // close specific position
strategy.close()         // close any open position

strategy.position_size

Read-only property indicating the current position state:

Value	Meaning
0	Flat (no position)
1	Long
-1	Short

if (strategy.position_size === 0) {
  // No open position — look for entries
}

Backtest Stats

After a strategy runs, Tradify Charts computes these statistics:

Stat	Description
totalTrades	Number of completed round-trip trades
winRate	Fraction of winning trades (0–1)
totalPnL	Sum of all trade PnLs
maxDrawdown	Largest peak-to-trough equity decline
sharpeRatio	Risk-adjusted return (mean / std dev)
profitFactor	Gross profit / gross loss
avgWin	Average profit on winning trades
avgLoss	Average loss on losing trades

Stats are displayed in the console output after execution.

Full Example

strategy('RSI Mean Reversion', { overlay: true })

const rsi = ta.rsi(close, 14)
const atr = ta.atr(14)

if (rsi < 30 && strategy.position_size === 0) {
  strategy.entry('Long', 'long', {
    sl: close - atr * 2,
    tp: close + atr * 3,
  })
}

if (rsi > 70) strategy.close('Long')
