Since mid-October, prorealtime proorder has stopped working at IG Securities.

Below is one of the scripts that stopped working.

If anyone knows the cause,
I would appreciate it if you could tell me how to fix it.

// Parameters
deltaThreshold = 100 // Threshold for cumulative delta to determine trend
shortMA = 10 // Short Moving Average period
longMA = 50 // Long Moving Average period
rocPeriod = 14 // Period for Rate of Change (RoC)

// Variables
delta = 0
cumulativeDelta = 0

// Calculate Cumulative Delta
if close > open then
delta = volume
elsif close < open then
delta = -volume
else
delta = 0
endif

cumulativeDelta = cumulativeDelta + delta

// Calculate Moving Averages
shortMAValue = average[shortMA](close)
longMAValue = average[longMA](close)

// Calculate Rate of Change (RoC) for Volatility
rocValue = (close - close[rocPeriod]) / close[rocPeriod]

// Trading Strategy with Volatility Filter
if cumulativeDelta > deltaThreshold and shortMAValue > longMAValue and abs(rocValue) > 0.02 then
buy 0.1 share at market
set stop loss 20
set target profit 40
elsif cumulativeDelta < -deltaThreshold and shortMAValue < longMAValue and abs(rocValue) > 0.02 then
sellshort 0.1 share at market
set stop loss 20
set target profit 40
endif
