EA Trading Robot - Highest High, Lowest Low - Keltner Channel

Looking for a programmer to code a trading robot of stocks in the Brazilian B3 stocks market. 

It's a very simple robot that follows the market trend and trades as follows: 

In a bull trend:

Analyse N candles in the past and place limit order to buy in the lowest low of the N candles. Place stop gain order in the highest high of the last N candles. 

In a bear trend:

Analyse N candles in the past and place limit order to buy in the highest high of the N candles. Place stop gain order in the lowest low of the last N candles. 

Buy/sell signal: To determine if place buy or sell order, only trade long if close is above keltner channel upper line and only trade short if close is below keltner lower line. 

Every new candle, the stops will be replaced to the new highest or lowest of n candles according to the input. 

Inputs from the user

Qty of Candles to be analyzed (n candles from 2 to 10)

Keltner Channel ATR multiplier (from 0.0 to 3.0)

Period of Keltner Channel (2 to 50) 

Type of Keltner (Simple, exponential, welles wilder or weighted)

Candles to stop (a must would be to also implement a stop over time, in n candles, if input from user) 

Robot will be used in swing trade in timeframe D1, so orders have to be placed next day after 9:45 am when market opens in Brazil. But also want to use in 120m time frame. 

Please apply if you can code that. 

Is my first time working with MT5/MQL5 so if any other input needed please let me know.
