EA Functions required: 

Upon attached the chart , Check for any open positions. if any positions running then dont enter the trade and alert the user with "Positions Existing. EA Not Allowed to trade." 

If no positions, Open a buy or a sell  market order depending (Initial_Buy_0r_Sell) value with (Lot_Size) and (TP) . 


Next check the values of  External parameters:  (Add_Trend_Or_Range )    and   ( Add_Trend_Or_range_Type)

 if  Add_Trend_Or_Range  = Trend , Add_Trend_Or_range_Type = Pending . then,
 place a buystop and a sellstop order (Pips_Gap) away from last opened order price with lot increment and set TP.

Any one of the pending order executed(now this is the last opened order ) then delete the other one  and place new pending orders (Pips_Gap) away from last opened order price with lot increment.
Pending orders volume increment (Lot_Multiplier) should be applied to the sequence of orders of one direction.




 or   if  Add_Trend_Or_Range = Range, Add_Trend_Or_range_Type = Pending. then,
 place a buylimit and a selllimit order (Pips_Gap)  away from last opened order price with lot increment and set TP.


Any one of the pending order executed (now this is the last opened order )then delete the other one  and place new pending orders (Pips_Gap) away from last opened order price with lot increment.
Pending orders volume increment (Lot_Multiplier) should be applied to sequence of orders of one direction. 


Add_Trend_Or_range_Type=Market . then use market orders instead of pending orders for open addtional orders when price moves (Pips_Gap) difference from last order price. 



Pending order lot calculation Example: 

if lot multiplier =2 ,
initial lot size =0.1 ,
buy orders total=5,
sell orders total=3
 then volumes should be  
buy1=0.1
buy2=0.2
buy3=0.4
buy4=0.8
buy 5=0.16
sell1=0.1
sell2=0.2
sell3=0.4


When account profit or loss reached a predefined levels (Max_Profit & Max_Loss) all orders should be closed and  send notification to mobile .

EA should have 2,3,4,5 digits and multicurrency trading competablity.
