   UNIVERSAL EA

   This EA is to be based on buying /selling via buffers. 
   This is based on the calling of a custom signal indicator. 
   Here are the INPUTS below and I will give a description of how each INPUT works. Please see below. 
   Source code needs to be provided on completion of project.

   TP Mode.
   BASKET means for ALL trades to close out based on the TP/SL- OR Trail SL OR Break Even... 
   Basically its basket and everything closes based on the INPUTS. These figures are based on $, not pips

   INDIVIDUAL means that ALL trades are closed out based on Individual circumstances of TP/SL/ Trail/ Breakeven etc etc. 
   These figures are based on $, not pips

   LOT Size.
   This is standard and needs for no explanation.

   TP (IN $)
   This means that all trades either in basket or individual will close out based on this $ amount. Simple

   SL (IN $)
   This means that all trades either in basket or individual will close out based on this $ amount. Simple

   Trail TP (IN $)
   This means that at this point of $ then the Trail of price will commence and will only be closed out be the Trail Step. 
   This is for basket or Individual.

   Trail Step (IN $)
   This means that when price in the Trail TP is reached. As price goes up or down, the Trail Step will close out trades based on this Step. 
   Example is.

   Trail TP is set to $350,
   Trail Step is set to $50,
   Profit in trades is at $350,
   Profit in trades falls back to $300.
   Trades close out.
   As profit rises then the step is rising with the profit at the same step level as the INPUT. SIMPLE. 
   This is seen as trailing the high water mark.

   Break Even (IN $)
   This means that either basket or individual will close out at this level.

   Custom Indicator Name
   This is where the custom indicator will go for this EA to call from the folder.

   Buy Buffer
   This is the number for the buffer for buying

   Sell Buffer
   This is the number for the buffer for selling

   Use Break Even
   This means the option to use break even feature or not

   Use Trailing Stop
   This means the option to use trailing stop feature or not

   Use Close Out
   This means the option to close out feature or not

   Close Out Trades Level
   This means for the trades to be closed out at this level based on the “Close Out Trades Style” INPUT.
   I have added this feature because most brokers only allow a set amount of trades or pending orders. 
   So in this case the trades will close out ONLY 2 at a time based on the STYLE INPUT BELOW. 
   Obviously, trades will continue to be taken based on the entry criteria and in this case the trades will continue to close at this level as well. 
   In this case we will have trades closing at this level and trades also being entered based on the entry criteria 
   and trades also being closed out based on all the other INPUTS of TP/SL/Trailing/or Breakeven- based on basket or individual.

   Close Out Trades Level
   This is the level at which the 2 trades to close out will commence. This might be ranging from 10 to 500. 
   Depending on broker and system I use this for. Point to make is that 2 trades close out at the same time based on the “CLOSE OUT STYLE” INPUT

   Close out Trades Style
   This is the STYLE in which the 2 trades will close out when the “CLOSE OUT TRADES LEVEL” is reached.

   Break Even. This means that the 2 trades to close should be the 2 trades closest to receiving a Break Even result. MUST BE A BUY AND SELL TRADE.  
   So a positive trade of $ 1.95 should be paired with the closest trade to receive a Break Even result. 
   This could be a negative trade of -$1.45. Either way the object is clear, the result to gain is that the 2 trades to close 
   give the closest to break even as possible.

   Profit. This means the same as above INPUT yet the 2 trades to close out give the biggest profit. MUST BE A BUY AND SELL TRADE. Simple. 
   Best 2 trades at the time of closing to give biggest PROFIT.

   Magic Number
   This is obvious.
