Hi All,

I have an automated trading strategy which calls the Adaptive ATR-ADX Trend indicator from within the strategy code. The strategy works perfectly when backtesting however, when I go live in automatic trading it gets stopped by IG/PRT after the close of the first 5 minute candle and the attached reason for stopping pops up – server.strategy.probacktest.error.missing_data.call 

I’ve increased the DEFPARAM PreLoadBars to 20,000 and still no difference. Checked that the indicator name aligns with the code etc.. Tried loads of different call variations and still no joy. Below is an example of one of the strategy indicator call code blocks which did not work! Any advice would be hugely appreciated:

// =====================================================================
// ATR/ADX from indicator — guarded CALL (stable live, baseline results)
// =====================================================================
tAtrStop   = close
tTrendDir  = 1
tADX       = 0
tAtrUp2    = 0
tAtrDown2  = 0

// Keep this modest so you’re not waiting ages live; adjust if needed.
// 8 bars = 40 minutes on 5m.
safeMinBarsForCall = 8

// Only CALL after enough bars to avoid first-bar live hiccups
IF BarIndex >= safeMinBarsForCall THEN
tAtrStop, tTrendDir, tADX, tAtrUp2, tAtrDown2 = CALL "ATRADX_SAFE"
ENDIF

// Readiness (only gates entries; CALL itself is above)
IF useATRModule THEN
atrReady = (tADX > 0) OR (BarIndex >= safeMinBarsForCall)
ELSE
atrReady = 1
ENDIF

// Route to live vars (once ready) or harmless stubs before
IF useATRModule AND atrReady THEN
atrStop  = tAtrStop
trendDir = tTrendDir
aADX     = tADX
atrUp2   = tAtrUp2
atrDown2 = tAtrDown2
ELSE
atrStop  = close   // price-level stub so distance checks don’t blow up
trendDir = 1
aADX     = 0
atrUp2   = 0
atrDown2 = 0
ENDIF
