Simple TradingView PINE script for RSI backtesting strategy

I need a pine script, which will allow me to backtest a strategy. 1. ENTER LONG or CLOSE SHORT when RSI (close, 14) has crossed 0.30 returning from below. IMPORTANT!!! - on a candle close. 2. ENTER SHORT or CLOSE LONG when RSI (close, 14) has crossed 0.70 returning from above. On a candle close. 3. Don't open new position if there is already a position in the same direction opened. 4. Stop-loss at -2 pips. 5. Use 10% of total deposit per trade. So in most typical behaviour, when RSI crosses 0.30 or 0.70, two trade calls should be executed: trade close and opening a new one in the opposite direction. I would like to Backtest this strategy in a "Strategy Tester" over a configurable period of time, like 30 days.
