Custom Indicator / Expert Advisor Modification

I have an EA that enters a trade on every candle close on any timeframe I choose. If I choose only buys and choose a specific Timeframe,it buys only when there is a bullish candle formed. and the sells is also the same. It has a dashboard that has all the parameters associated with it. I want some modifications to the Trailing stop and then I want that the EA only places the trade (in an Buy trend) when there is a bullish engulfing of the bearish candle before that. So the Ea will only place trades when

1. Trailing Stop Modification: I'd like to enhance how the trailing stop works in my EA. The trailing stop is like a flexible stop-loss level that adjusts as my trade goes in my favor. I want to improve this feature to make it more effective.

2. Entry Condition Modification: I want the EA to be more selective when entering trades:

• For buy trades, I want it to enter only when I see a series of bullish candles forming one after the other, without any bearish candles in between.
• In the case of a bearish candle appearing during an uptrend, I want the EA to enter a trade only if there's a bullish engulfing candle right after that bearish one.
3. Custom Sell and Buy: the custom buy and sell button on my EA doesnt work.I want it in a way that when i press on the buy or sell. the EA should enter a buy or sell trade directly. There is a pause button too and i want it to change to play when i click on it.
   
   
4. News Filter: I want a news filter combined in a sense that I will be able to know the upcoming news and I will get a prompt of the type of news and the time.
   
   
5. Buy/Sell only Button: I want a new dashboard item so I know that the EA is in a Buy only trend or sell depending on what i choose when configuring it.
