EA BASED ON PRICE LEVELS (martingale system)

I need an EA based on Price levels

EA settings- 

lot size - should be able to change . default is 0.01

Lot Multiplier - Should be able to change . default is 2

Gap between buy price and sell price.- should be able to change . default is 2 pips.

take profit- should be able to change . default is 10 pips.

STRATEGY-

   As EA is attached to chart. at price 'x' then when price moves 1pip above 'x' then buy 0.01 lot at buy price

when price moves below price 'x' at sell price (which is 1pip below) then sell 0.01 lot.

after buying at buy price / selling at sell price. if price moves opposite to the trade , then close trade at the opposite price level and open opposite trade of lot 0.02(0.01 X 2).

continue doing this until take profit is reached 

EXAMPLE-

TP for buy trade                              1.3540                                                                                     gap between buy price and sell price is 2 pips(as in setting)

Buy price                                          1.3530

Price X                                              1.3529

Sell price                                          1.3528

TP for sell trade                                1.3518

After price reaches buy price and then moves to sell price then close buy trade and open sell trade 2 times the lot size

NOTICE- allow slippage . EA should not miss placing the trade.

              AE should not miss placing 2 times the previous trade.

              EA should multiply loss trades until take profit is reached.

             once take profit is reached. then consider that price as Price'x' and continue the whole process again.
