Donchian ATR EA

I would like an EA made based on the following criteria.

Variable Donchian Channel

Variable ATR 

TP/SL based on ATR multiple

Period based exit

Variable Lot Sizes 

 Buy:

A buy is triggered when the price breaks the upper Donchian Channel.

Sell:

A sell is triggered when the price breaks the lower Donchian Channel.

Exit criteria is based on either the price reaching the S/L, T/P level or after a certain number of periods have passed.

Take Profits: based on a multiple of the Average True Range i.e. ATR is 15 Pips and the multiple is 3 so Take Profit would be 45 Pips

Stop Losses: based on a multiple of the Average True Range i.e. ATR is 15 Pips and the multiple is 2 so the Stop Loss would be 30 Pips

Period Based Exit: When a buy or sell is open after a certain number of periods have passed the order is automatically closed i.e. 1 hour time frame and the period is set for 6 hours. After six hours have passed the order is automatically closed at the end of the period.

I would also like the option to choose whether or not to exit based on 1. T/P and S/L,  2. Period Based only or 3. both whichever comes first
