Stochastic and signal line must be accurate in order to execute
1) the stochastic and signal must reach 80 or 90 to execute as sell
2) when stochastic and signal line approach 20 it will   close the order or take profit or stop loss
3) the stochastic and signal must reach 20 or 10 to execute as buy
4) when stochastic and signal line approach 80 it will   close the order or take profit or stop loss
5) existing ea have buy and sell at same time change to buy or sell at a time 
6) stochastic and signal must be accurate in order to execute 
7) back test the ea
8) make sure the ea dont execute between 11 to 89 at stochastic and signal line
