Scalping EA

I would like to have a scalping expert advisor, programmed in mql5, working based on tick data.

The program should take the Bid, Ask and Volume data of the current Tick and keep the record of the same information (Bid, Ask and Volume) of the last “TickCount” ticks (for example TickCount = 50).

If the difference between the price (Ask or Bid as described below) of the current tick and the minimum/maximum price (see below the entry details) of the last “TickCount” ticks is greater than DeltaPrice (pips), one entry condition is fulfilled.

The other condition is that the sum of volumes of the last “TickCount” ticks is greater than “VolumeLimit”.

The program will use a trailing stop, setting initially a Stop Loss at the “TrailingDistance” distance from the current price (Bid or Ask, as described below), and moving it every time when a new higher/lower price is achieved.

Parameters:

1.     TickCount

2.     DeltaPrice

3.     VolumeLimit

4.     TrailingDistance

Buy entry conditions

1.     (Current Ask – the minimum Ask of the last “TickCount” ticks) > DeltaPrice

AND

2.     (The sum of all Volumes of the last “TickCount” ticks) > VolumeLimit

Buy entry trailing stop

Set a trailing stop at (Current Ask – TrailingDistance)

After the position is opened, every time when (Ask– Stop Level) > TrailingDistance the Stop Level is moved at (Ask – TrailingDistance) position

Sell entry conditions

1.     (The maximum Bid of the last “TickCount” ticks – Current Bid) > DeltaPrice

AND

2.     (The sum of all Volumes of the last “TickCount” ticks) > VolumeLimit

Sell entry trailing stop

Set a trailing stop at (Current Bid + TrailingDistance)

After the position is opened, every time when (Stop Level - Bid) > TrailingDistance the Stop Level is moved at (Bid + TrailingDistance) position

Optimization

The expert advisor should use a customized optimization criterion, according to following formula:

             (Balance) * (Max Profit Factor) * (Max Sharpe Ratio)
