The most robust mode is set by default.
Improved indicator design.

Restrictions on timeframes have been removed. It is now a fully functional indicator!

1. Improved flat calculation algorithm, which is now considered for any averaging period.
2. Added arrows showing the moments of the change in the direction of the trend.
3. Three modes of visual display of information are made:
3.1) Only arrows showing the immediate direction of price movement and the moments of the trend change.
3.2) Averaged lines of price movement and arrows of the moments of a change in the direction of the trend.
3.3) Only the middle lines of price movement (as in the earlier version).
4. Four more algorithms for optimal filtering from market noise added (now there are 8 filtering algorithms in the indicator).

1. Added three new modes of operation with the following averaging algorithms
1) XC=XF - XS + SMMA
2) XF=<x/SMMA>*SMMA
3) XS=<x*SMMA>/SMMA,
where x are points of history, <...> is the averaging procedure.
2. Trading restrictions are set - only the H4 timeframe can be used.

Added push and mail alert types.
