Simple stochastic EA needed

Hi

I need a simple EA which would use Stochastic Oscillator to place trades

Conditions:

EA would open short positions if stochastic oscillator slow and fast line are above 70 and fast line crosses the slow line (both being still above 70 level)

EA will open short position as a stop order 1 pip below the low of the candle on which the cross took place. Example in the screenshot below

Ea would have option to change stochastic K period and D period and slowing.

It would have two money management options

1.

Ordinary stop loss/take profit

2.

Hold positions opened until opposite signal is generated.

It would have an option to close the position once new opposite signal is generated. Example:

EA opened short trade and after a while, stochastic are below 30 level and signal long trade, short position is now closed and long is opened.
