DAYTF = tsl.get_historical_data(tradingsymbol = stock_name,exchange = ‘NSE’,timeframe=“1day”)
TODAY_5MIN = tsl.get_historical_data(tradingsymbol = stock_name,exchange = ‘NSE’,timeframe=“5”) # this call has been updated to get_historical_data call,

	if (DAYTF is None) or (TODAY_5MIN is None) :
		continue

	if (DAYTF.empty) or (TODAY_5MIN.empty):
		continue
		

	# Conditions to fetch yesterdays data (high and low and close) 
	yesterday      = DAYTF.iloc[-1]  #pandas  yesterday completed candle 
	return PDH = yesterday['high'],
	return PDL = yesterday['low'], 
	return PD_open = yesterday['open']
	return PD_close = yesterday['close']

	# coditions to fetch current day's open
	today          = DAYTF.iloc[0]
	return Today_OPEN = today['open']

	#conditions to check gap_up or gap_down and bullish or bearish yesterday's daily candle
	gap_up            = Today_OPEN > PD_close
	gap_down          = Today_OPEN < PD_close
	yesterday_bullish = PD_close > PD_open
	yesterday_bearish = PD_close < PD_open 

	# Conditions that are on 5 minute timeframe
			
	cc_5           = TODAY_5MIN.iloc[-1]   # pandas
	prev_cc_5      = TODAY_5MIN.iloc[-2]
	third_cc_5     = TODAY_5MIN.iloc[-3]

Same difficulty i am facing.

i have logic and made some improvement but since i am not a python coder, i am facing challenges in executing it smoothly. I use dhan cloud. @Tradehull_Imran Please help.

for intraday only-

i am using 1min,3min,5min candle with bb,rsi,ema.

if certain condtion met, trade should initiate.

exit based on 3min ema9_smooth9 or target reach or trail stop loss.

Kindly let me know your available time to connect with you.

Hi @Vidur ,

Refer the pseudocode -

# Intraday strategy pseudocode

while market_is_open:

    get_1min_3min_5min_candles()

    calculate_BB_RSI_EMA()

    if no_open_position:

        if buy_condition_met:
            enter_buy()
            set_target()
            set_trailing_stop()

        elif sell_condition_met:
            enter_sell()
            set_target()
            set_trailing_stop()

    else:

        update_trailing_stop()

        if target_reached:
            exit_trade("TARGET")

        elif trailing_stop_hit:
            exit_trade("TRAIL STOP")

        elif three_min_ema9_crosses_ema9_smooth9:
            exit_trade("EMA EXIT")

    if force_exit_time_reached:
        exit_open_trade()
        stop_strategy()

Hi @Vidur ,

Market orders cannot be placed through the API due to the latest SEBI guidelines. Change the order type and check once.
