// --- Calculations ---
// Request the ATR calculation specifically from the 1-minute timeframe
atrValue1min = request.security(syminfo.tickerid, "1", ta.atr(i_atrLength))

// Calculate initial Stop Loss distance in points using the ATR Multiplier
initialStopLossPoints = atrValue1min * i_atrMultiplier

// Round the Stop Loss points DOWN to the nearest multiple of 5
// Example: 31.2 -> floor(31.2 / 5) * 5 = floor(6.24) * 5 = 6 * 5 = 30
// Example: 34.2 -> floor(34.2 / 5) * 5 = floor(6.84) * 5 = 6 * 5 = 30
// Example: 29.9 -> floor(29.9 / 5) * 5 = floor(5.98) * 5 = 5 * 5 = 25
// Example: 35.1 -> floor(35.1 / 5) * 5 = floor(7.02) * 5 = 7 * 5 = 35
roundedStopLossPoints = initialStopLossPoints > 0 ? math.floor(initialStopLossPoints / 5) * 5 : 0.0 // Avoid division by zero if ATR is 0/na

// Calculate Risk per single contract based on the ROUNDED SL distance in points and point value
riskPerContract = roundedStopLossPoints * i_pointValue

// Calculate Position Size (Number of Contracts)
// Divide total *desired* risk by the (updated) risk per contract. Use math.floor() to round DOWN.
positionSizeContracts = riskPerContract > 0 ? math.floor(i_riskAmount / riskPerContract) : 0.0

// Calculate the ACTUAL dollar risk based on the final number of contracts and the risk per contract
actualRiskAmount = positionSizeContracts * riskPerContract
