Trailing Takeprofit at Breakeven for Buy &/or Sell

I need to modify OP with the same takeprofit; set for breakeven no matter if buys, sell or both.

The takeprofit must follow a trend indicator as to which side it must be placed.

example: trend is sell so TP is set below price, and above price if trend is buy.

:Let me further explain:

When my strategy fails to exit within a few bars there can be adding of orders.

There can be same OP type, and there can even be mixed OP type, and the takeprofit should be set to a price that means it is breakeven(optional) following a trend for which side of price to put the take profit.

I have a working EA with all the steps needed for entering the TP trailing methods

Incase price surpasses the TP before setting it orders must be closed clientside.

This is where I need work on

void ManageTP()
 {
 //initial TP after two bars for cumulative profit
 if( OrderBarsOpen==1 && LastOpenBar==2 )
  {
  //if TP to be set is surpassed by open price then close all trades
  
  //set TP for all orders to breakeven & 1 point profit
  
  }
 //cumulative profit exits
 if( OrderBarsOpen>1 && LastOpenBar>2 )
  {
  //trail takeprofit by trend, sell=below price & buy=above price
  switch(iST(0))
   {
   case 2: //sell trend
    //if TP to be set is surpassed by open price then close all trades
    
    //set TP for all orders to breakeven & 1 point profit below price
    
    break;
   case 1: //buy trend
    //if TP to be set is surpassed by open price then close all trades
    
    //set TP for all orders to breakeven & 1 point profit above price
    
    break;
   default: break;
   }
  }
 TrailedThisBar=true;
 }
