Developing an Expert Advisor based on my strategy

Hello

What I need is an Expert Advisor (MT4) that executes my strategy and also ongoing support until the EA executes everything as i want.

Entries:
At 23.59 CET the EA has to put a buy and sell stop order at the high and low of the last 3 candles of the past day. In total there can be only 2 trades per day. One buy stop and one sell stop trade. At some days also only 1. It depends if both get triggered or not.
Timeframe: 1H

Stop Losses:
Along with the entry, the EA should also set the stop loss at the level of the entry of the other order. For example:
- For the buy stop order the stop loss will be at the same level where the sell stop entry would be. Or in other words, at the low of the last 3 candles of the past day.
- For the sell stop order the stop loss will be at the same level where the buy stop entry would be. Or in other words, at the high of the last 3 candles of the past day.
- I need a parameter to set the risk in % of whole capital per trade. The size of stoploss in pips in combination with the risk in % should automatically calculate the lot size for the pending.

- Trailing stop should be defined with a percentage of the distance from entry and current price. The trailing stop loss should be at 50% of the distance from the entry and the current price. I need a parameter for that percentage.
- The trailing stop should only get activated when 1:2 risk to reward is reached. Then the stop loss gets moved directly to 50% of the distance from the entry and the current price.
- When 1:1.5 risk to reward is reached the stop loss should get moved to breakeven / entry level

Trading Hours:
- Trading starts 23.59 CET -> buy and sell stop orders will be set in place then
- At 8pm CET all trades and orders will be closed if not already done by trailing stop

Kind regards

Tobias
