Hi,

I sparred with ChatGPT on this but it couldnt help me.

It suggested the below code, but no matter how much I asked it to adjust the code it didnt help.

I got an error message on the line concerning “position_size_percent” (line 4), “entry_dates” (line 6), and “profit_treshold” (line 8).

So basically I want to create a code that says BUY or SELL at certain dates in the future, with adjusting trailing stop losses and also adjusting for volatility.

Assistance would be greatly appreciated:)

// Parameters
DEFPARAM CumulateOrders = False

// Position size percentage
POSITION_SIZE_PERCENT = 5.0 // 5% of the total capital

// List of dates to go long (in YYYYMMDD format)

PROFIT_THRESHOLD_1 = 0.5 // Profit threshold of 0.5%
PROFIT_THRESHOLD_2 = 1.0 // Profit threshold of 1%
PROFIT_THRESHOLD_3 = 1.5 // Profit threshold of 1.5%
PROFIT_THRESHOLD_4 = 3.0 // Profit threshold of 3%

INITIAL_TRAILING_STOP_PERCENT = 2.0 // Initial trailing stop of 2%
TRAILING_STOP_1_PERCENT = 1.5 // Trailing stop of 1.5%
TRAILING_STOP_2_PERCENT = 1.0 // Trailing stop of 1%
TRAILING_STOP_3_PERCENT = 0.75 // Trailing stop of 0.75%
TRAILING_STOP_4_PERCENT = 0.5 // Trailing stop of 0.5%

// Variables
var trailing_stop = 0.0
var entry_price = 0.0
var contracts_to_trade = 0

// Calculate the last 10 days historical volatility
historical_volatility = Std[10](Close)

// Adjust position size and trailing stop loss based on historical volatility
adjusted_position_size_percent = POSITION_SIZE_PERCENT * (historical_volatility / 0.01) // Assuming 0.01 as a reference volatility

// Conditions to enter long positions
IF NOT LongOnMarket THEN
FOR i = 0 TO (ArraySize(ENTRY_DATES) – 1) DO

// Calculate the number of contracts to trade
contracts_to_trade = (adjusted_position_size_percent * StrategyAccountEquity) / Close
contracts_to_trade = Round(contracts_to_trade) // Ensure it’s an integer value

entry_price = Close
trailing_stop = adjusted_initial_trailing_stop
BUY contracts_to_trade CONTRACTS AT MARKET
BREAK // Exit loop once position is opened
ENDIF
NEXT
ENDIF

// Conditions to exit long positions
IF LongOnMarket THEN
// Calculate the current profit percentage
current_profit = (Close – entry_price) / entry_price * 100

// Adjust the trailing stop based on profit thresholds

ELSIF current_profit >= PROFIT_THRESHOLD_2 THEN

ELSIF current_profit >= PROFIT_THRESHOLD_1 THEN
trailing_stop = TRAILING_STOP_1_PERCENT * (historical_volatility / 0.01)
ELSE
trailing_stop = adjusted_initial_trailing_stop
ENDIF

// Set the trailing stop price
trailing_stop_price = entry_price * (1 – trailing_stop / 100)

// If the current price falls below the trailing stop price, close the position
IF Close <= trailing_stop_price THEN
SELL AT MARKET
