SimTradeIndicators
Library "SimTradeIndicators"
SimTrade indicator library — exact parity with Python pipeline (TA-Lib + pandas_ta).
Each function replicates the formula used in base.py / signals.py so that
TradingView charts match the GPU hunt / validator / live engine outputs.
Formula sources:
TA-Lib → RSI, ATR, EMA, MACD, CCI, Stoch, WILLR, MFI, ADX, PSAR, OBV, BBANDS, AROON, PPO, AD
pandas_ta → SuperTrend, Vortex, Ichimoku, Donchian, HMA, TSI, CMF, EFI, CHOP, Heikin-Ashi
Manual → Keltner (EMA+ATR Wilder), TTM Squeeze, Chandelier Exit, VWAP reset, Pivot Points
Known intentional deviations (documented):
- Stoch trigger 11 uses Full %D (double-smoothed), not single %K
- OBV filter 206 uses windowed 800-bar OBV (GPU-aligned, not cumulative)
- Pivot Points use rolling window, not session-based (see pivot_pp notes)
- EMA has longer warmup in TA-Lib (~50 bars unstable period) vs TW (from bar 1); steady-state identical

donchian_val(length)
Donchian Channel. Returns [upper, mid, lower].
upper = highest(high, N), lower = lowest(low, N). Matches pandas_ta.donchian.
NOTE: lookback may differ ±1 bar from TA-Lib; consistent across all pipeline stages.
Trigger 37 (donchian_break) compares close > upper[i-1] — use upper[1] in Pine.
Parameters:
length (simple int): Period (default 20)
Returns: [upper, mid, lower]
ttm_squeeze_val(bb_period, bb_mult, kc_period, kc_mult)
TTM Squeeze. Returns [squeeze_on, momentum].
squeeze_on: BB inside KC (volatility compression).
momentum: ta.linreg(close − (donchian_mid + SMA) / 2, bb_period)
EXACT match with John Carter formula and base.ttm_squeeze after fix.
Parameters:
bb_period (simple int): BB period (default 20)
bb_mult (float): BB multiplier (default 2.0)
kc_period (simple int): KC period — same for EMA midline and ATR band (default 20)
kc_mult (float): KC ATR multiplier (default 1.5)
Returns: [squeeze_on (bool), momentum (float)]
chandelier_val(period, mult)
Chandelier Exit. Returns [long_exit, short_exit].
long_exit = highest(high, period) − mult · ATR(period)
short_exit = lowest(low, period) + mult · ATR(period)
Exact match with base.chandelier_exit. Both include current bar in rolling max/min.
Trigger 45 fires when close crosses long_exit or short_exit (up = bull, down = bear).
Parameters:
period (simple int): Lookback and ATR period (default 22)
mult (float): ATR multiplier (default 3.0)
Returns: [long_exit, short_exit]
ha_close()
Heikin Ashi close. HA_close = (open + high + low + close) / 4. Matches pandas_ta.ha.
Returns: HA close value
ha_open()
Heikin Ashi open. HA_open = (HA_open[i-1] + HA_close[i-1]) / 2.
Trigger 48 fires on HA candle color flip: HA_close vs HA_open.
Returns: HA open value
pivot_pp(period)
Rolling Pivot Point (floor method). Matches base.pivot_points.
pp = (max(high, period bars ago) + min(low, period bars ago) + close[1]) / 3
NOTE: Rolling window, NOT session-based. H1 default period=24 ≈ 1 day (crypto 24/7).
For H4 set period=6 (6 × 4h = 1 day). TW Pivot Points use session H/L/C — differs.
Parameters:
period (simple int): Rolling lookback (default 24)
Returns: Pivot point value
pivot_r1_s1(period)
Rolling R1 and S1 levels. Matches base.pivot_points r1/s1.
r1 = 2·pp − lowest_low, s1 = 2·pp − highest_high
Parameters:
period (simple int): Rolling lookback (default 24)
Returns: [r1, s1]
