The world has changed.. I feel it in water, I feel it in the ground,

I feel in air. Much, that was before - will not return never..

The idea of creation Gandalf_PRO EA is taken from this branch of a forum.Drum kit for fl studio.

The EA holds open one buy and one sell orders (without dependence from each other)

Until the market of them will not close with fixed TP or SL.

The input in the market occurs on the basis of two-parametrical Exponential Smoothings

Time Series in view of 2 parameters:

1-st parameter: it is parameter of accommodation of the price-S,

2-nd parameter: it is parameter of an inclination of trend T,

Calculations go under recurrent formulas:

S [n] =w*y [n] + (1-w) * (S [n-1] +T [n-1])

T [n] =t * (S [n]-S [n-1]) + (1-t) *T [n-1]

Then, the predicted value: y [n+1] =S [n] +T [n]

As initial (i.e. initial) values (estimations) for 1-st and 2-nd parameter it is possible

To take factors from the formula of linear regress - from here.

Entrance variables in the EA :

For longs:

In_BUY=true; long positions allowed,

Count_buy=24; number of bars in a history on which smooths out ВР,

w_price=0.18; factor of the price,

w_trend=0.18; factor of a trend,

SL_buy=62; a level stoploss in pips,

Risk_buy=0; a risk level in % .

For shorts: variablesIn_SELL, Count_sell, m_price, m_trend, SL_sell, Risk_sell- are similar.

Optimization passes in 2 stages, on constant lot, i.e. when Risk_buy=0; and Risk_sell =0;

Stage 1, for longs: In_BUY=true; In_SELL=false; Count_buy from 3 up to 120, with step 1;

w_price and w_trend from 0.05 up to 0.6 with step 0.01; SL_buy from 30 up to 100, with step 1.

Stage 2, for shorts: In_BUY=false; In_SELL=true; the other-is similar.

The EA well trades on 'fat' sites of a trend on periods H4 and D - EURUSD,

However, the additional filtration is necessary for an input in the market with application of indicators

on the higher periods.
