MartinPro

MartinPro   (or Martingale Pro) is a martingale-based  scalper EA. It is recommended to be traded on only one pair at a time -- preferably Gold or GBPUSD.

You can set your initial FixLots based on increased equity or simply set the AutoLots to 'Yes' and the robot will use a computed initial lot size.

Default setting may be OK for most trades.  

Note that this is a martingale  EA; it starts with two opposite orders and opens additional (subsequent) orders with increased lot size and attempts to close all the trades at once when the required profit percentage is met. The EA is expected to run continually, hence the need for VPS where you do not  have continual electricity and internet.

Parameters are as follows:

FixLots: This is the initial lot size, if the UseAutoLots is 'No'.

UseAutoLots: If this is 'Yes', the EA will ignore the FixLots and tries to calculate an initial lot size based on available equity and a percentage risk.

MaximumTradeableSpread: The allowable spread to open orders.

MinimumPercentProfit: Percentage of profit needed to close all orders, if UseAutoProfits is 'No'.

UseAutoProfits: If this is 'Yes', the MinimumPercentProfit will be ignored and profit percent will be calculated on 1/4th of the maximum Draw Down.

MaximumSlippage: Allowable Slippage to open or close orders.

MaximumGridTrades: This is what makes the EA martingale. The number of additional orders that can be opened with incremental lot size. The increment is based on Fibonacci.

MaximumConcurrentTrades: If you decide to trade more than one pair; this can be used to limit the number of openable trades across the pairs.
