Example:
WriteVal( BeginValue( DateTime() ), formatDateTime );
WriteVal( EndValue( DateTime() ), formatDateTime );

>CHANGES FOR VERSION
4.28.0 (as compared to 4.27.1)
·
ApplyStop has one more parameter
ApplyStop( Type, Mode, Amount, ExitAtStop, Volatile = False )
new Volatile parameters decides if amount (or distance) (3rd parameter) is
sampled at the trade entry and remains fixed during the trade (Volatile = FALSE
- old behaviour) or if can vary during the trade (Volatile = TRUE)
Allows single-line implementation of Chandeliers exit:
ApplyStop(stopTypeTrailing, stopModePoint,
3*ATR(14), True, True );
·
ApplyStop handles new N-Bar stop - exits the trade
after N bars.
Type = stopTypeNBar; /* = 3 */
Mode = stopModeBars; /* = 1 */
ApplyStop( stopTypeNBar, stopModeBars, 5 ); //
exits trades on 5th bar since entry
·
added new "Reverse entry signal forces
exit" check box to the Backtester settings.
When it is ON (the default setting) - backtester works as in previous versions
and closes already open positon if new entry signal in reverse direction is
encountered. If this switch is OFF - even if reverse signal occurs backtester
maintains currently open trade and does not close positon until regular exit
(sell or cover) signal is generated.
In other words when this switch is OFF backtester ignores Short signals during
long trades and ignores Buy signals during short trades.
·
added "Allow same bar exit (single bar
trade)" option to the Settings
When it is ON (the default settings) - entry and exit at the very same bar is
allowed (as in previous versions)
if it is OFF - exit can happen starting from next bar only (this applies to
regular signals,there is a separate setting for ApplyStop-generated exits).
Switching it to OFF allows to reproduce the behaviour of MS backtester that is
not able to handle same day exits.
·
long trades now take precedence over short trades
so if signals happen on the same bar in both directions only long trade is
taken.
·
new AFL functions:
DateTime() - returns array of encoded date/time values suitable for using with
AddColumn and formatDateTime constant
to produce date time formated according to your system settings
AddColumn( DateTime(), "Date / Time",
formatDateTime );
new formatChar constant allows outputting single ASCII character codes:
Example (produces signal file accepted by various other programs):
Buy=Cross(MACD(),Signal());<font
face="Courier New">
Sell=Cross(Signal(), MACD());
Filter=Buy OR Sell;
SetOption("NoDefaultColumns", True );
AddColumn( DateTime(), "Date",
formatDateTime );
AddColumn( IIf( Buy, 66, 83 ),
"Signal", formatChar );
·
new AFL functions continued:
BarIndex() - returns zero-based bar number -
the same as Cum(1)-1 but it is much faster than Cum(1) when used in Indicators
SetOption( "name", value )
- sets various options in automatic analysis settings currently available
options are
"NoDefaultColumns" - if set to True - exploration does not have
default Ticker and Date/Time columns
"InitialEquity"
"AllowSameBarExit"
"ActivateStopsImmediately"
"AllowPositionShrinking"
"FuturesMode"
"InterestRate"
·
if you overwrite AA settings via
SetTradeDelays/SetOption
backtest report gives these actual values instead of originaly set in the
settings
·
new Null constant is equal to -1e10 (empty value)
so you can use it instead enigmatic -1e10
obsolete styleLog removed (logarithmic scale setting is not per-line but
per-pane and it is selectable from Indicator Builder)
·
added PlotGrid( level, color = colorDefault )
function that plots grid line using built-in dotted style.

Random( seed = none ); function takes new parameter
seed.
If seed is defined it initializes the seed of random number generator this
allows to produce repetitive series of pseudo-random series. If seed is not
specified - random number generator continues generation.
To reinitialize the generator, use 1 as the seed argument. Any other value for
seed sets the generator to a random starting point.
Example 1:
Graph0 = Random(); // generates different sequence with each refresh
Example 2:
Graph0 = Random(1); // generates the same sequence with each refresh
