The analysis of this Expert Advisor is based on the theory that the market must accumulate certain "step volume" when moving from point X to point Y. Simply put, if the rates go 100 points up, then it must pass a total of 2000 points up and down.

The EA opens one buy and one sell market order. It places StopLoss for each order. The orders counterbalance each other so the account balance cannot go into a large drawdown. The EA analyzes the market, moves the StopLoss of each order if the "step volume" is insufficient. As soon as the "step volume" meets the conditions one of the orders is closed by StopLoss. A TrallingStop (input parameters) is places for the other order.

The EA implements the ability to trade a fixed volume - the Lots parameter, or to use an automatic volume - the Auto_Lots parameter (recalculated based on the account balance)

Input Parameters:

1. Lots - volume for opening Buy and Sell market orders;
2. Auto_Lots - automatic recalculation of the volume for opening an order (not used if Auto_Lots =0);
3. StopLoss - StopLoss level of the Buy and Sell orders in points;
4. TrallingStop - TrallingStop level of the Buy and Sell orders in points;
5. Magic_buy - the magic number of the Buy order;
6. Magic_sell - the magic number of the Sell order;

Recommended inputs for 4-digit quotes:

1. Lots = 0.1;
2. Auto_Lots = 5;
3. StopLoss = 10;
4. TrallingStop = 4;
5. Magic_buy = 1;
6. Magic_sell = 2;

Recommended inputs for 5-digit quotes:

1. Lots = 0.1;
2. Auto_Lots = 5;
3. StopLoss = 100;
4. TrallingStop = 40;
5. Magic_buy = 1;
6. Magic_sell = 2;

The EA has been tested on the EUR/USD pair. But it also shows good results on other pairs.

And from me: "Everything is good in moderation, even Forex".
