market is been raising for 2 days in a row, current close is higher than previous close, current low is higher than previous low, current close is higher than previous close and the current close is above 21-period simple moving average.
we sell at the close when:
current close is higher than previous day's high.

Commission is set to $2.5 per side and slippage is set to 1 tick.
You can adjust commission for your instrument, as well play around with the moving average period.
