-stoch(14,3,3) first time cross above 80 after bar close ( compared to last below 20)

-sginal up arrow displayed after bar close.

exit buy : stoch cross below 20 after bar close

entry sell:

-current bar breakout  previews n days low after bar close (defaut 3 days), means current bar low > previews n days low

-stoch(14,3,3) first time cross below20 after bar close ( compared to last above 80)

make this strategy as indicator first, then make it to EA with regular money management such as fixed lot, % of balance, etc.
