Development of EA based on adx and pending stop order

hello,

i want to develop an ea based on :

rule 1 : ADX indicator if above value 20 , ( if adx fall below 20, pending order will close and no order will be open)

rule 2 :  ea will open buy and sell stop order when candle close. If not trigger within the hour. It will open the next candle open and close price the new buy and sell stop and so on.

When order trigger, it will set 50 pips stoploss and use auto trailing stop, no take profit.

also included ea lock to account number.

In the settings 

ADX value :

stoploss :

Auto trailing value : 

The ea is based on timeframe it is being put. by default it is h1.

i attach pictures to better explain on what i mean. thank you
