I am new to trading view and have very little programming background. I am trying to write a simple strategy to buy when RSI hits 30 and sell when the price rises by 5% after my entry.

I am not sure how to go about exiting the trade. See code below, can you help me out please?

```fromYear = year >= 2010
toYear = year <= 2020

longCondition = rsi(close, 21) < 30
if (longCondition and fromYear and toYear)
strategy.entry(Long 1, strategy.long)

entry_price = valuewhen(longCondition, open, 0)
exit_price = entry_price * 1.05

closeCondition = exit_price
if (closeCondition)
strategy.close(Long 1)```

Seems like the first line of code is missing from above,

strategy(Simple RSI, overlay=true, initial_capital=10000, currency='USD')
fromYear = year >= 2010
toYear = year <= 2020

longCondition = rsi(close, 21) < 30
if (longCondition and fromYear and toYear)
strategy.entry(Long 1, strategy.long)

entry_price = valuewhen(longCondition, open, 0)
exit_price = entry_price * 1.05

closeCondition = exit_price
if (closeCondition)
strategy.close(Long 1)

Hi

I would do

entry_price = valuewhen(longCondition, close, 0)
exit_price = crossover(entry_price, entry_price * 1.05)

if (exit_price)
  strategy.close("Long")
