٢٠ أبريل ٢٠٢٣

hello everyone, i wrote a code for a bot i want to create but will need help in correcting some few erros as i cannot get it to work with trading view.
here it is:\
//version=5
study("My Indicator")

// Define EMA variables
ema50 = ema(close, 50)
ema200 = ema(close, 200)

// Define ADX variable
adxVal = adx(14)

// Define RSI variable
rsiVal = rsi(close, 14)

// Buy Signal
if (ema50 > ema200 and adxVal > 30 and rsiVal < 70 and volume > average(volume, 50))
strategy.entry("Buy", strategy.long)

// Sell Signal
if (ema50 < ema200 and adxVal < 30 and rsiVal > 70 and volume > average(volume, 50))
strategy.entry("Sell", strategy.short)
