Candlestick Patterns
Hikkake Modified
Introduction
Create a new Hikkake Modified candlestick pattern to indicate the pattern's presence.
To view the implementation of this candlestick pattern, see the LEAN GitHub repository.
Using HikkakeModified Indicator
To create an automatic indicators for HikkakeModified, call the HikkakeModified helper method from the QCAlgorithm class. The HikkakeModified method creates a HikkakeModified object, hooks it up for automatic updates, and returns it so you can used it in your algorithm. In most cases, you should call the helper method in the Initializeinitialize method.
public class HikkakeModifiedAlgorithm : QCAlgorithm
{
private Symbol _symbol;
private HikkakeModified _hikkakemodified;
public override void Initialize()
{
_symbol = AddEquity("SPY", Resolution.Daily).Symbol;
_hikkakemodified = CandlestickPatterns.HikkakeModified(_symbol);
}
public override void OnData(Slice data)
{
if (_hikkakemodified.IsReady)
{
// The current value of _hikkakemodified is represented by itself (_hikkakemodified)
// or _hikkakemodified.Current.Value
Plot("HikkakeModified", "hikkakemodified", _hikkakemodified);
}
}
} class HikkakeModifiedAlgorithm(QCAlgorithm):
def initialize(self) -> None:
self._symbol = self.add_equity("SPY", Resolution.DAILY).symbol
self._hikkake_modified = self.candlestick_patterns.hikkake_modified(self._symbol)
def on_data(self, slice: Slice) -> None:
if self._hikkake_modified.is_ready:
# The current value of self._hikkake_modified is represented by self._hikkake_modified.current.value
self.plot("HikkakeModified", "hikkake_modified", self._hikkake_modified.current.value)
The following reference table describes the HikkakeModified method:
hikkake_modified(symbol, resolution=None, selector=None)Creates a new HikkakeModified pattern indicator. The indicator will be automatically updated on the given resolution.
- symbol (Symbol)
- resolution (Resolution, optional)
- selector (Callable[IBaseData, IBaseDataBar], optional)
HikkakeModified(symbol, resolution=None, selector=None)Creates a new HikkakeModified pattern indicator. The indicator will be automatically updated on the given resolution.
- symbol (Symbol)
- resolution (Resolution, optional)
- selector (Func<IBaseData, IBaseDataBar>, optional)
If you don't provide a resolution, it defaults to the security resolution. If you provide a resolution, it must be greater than or equal to the resolution of the security. For instance, if you subscribe to hourly data for a security, you should update its indicator with data that spans 1 hour or longer.
For more information about the selector argument, see Alternative Price Fields.
For more information about plotting indicators, see Plotting Indicators.
You can manually create a HikkakeModified indicator, so it doesn't automatically update. Manual indicators let you update their values with any data you choose.
Updating your indicator manually enables you to control when the indicator is updated and what data you use to update it. To manually update the indicator, call the Updateupdate method with a TradeBar. The indicator will only be ready after you prime it with enough data.
public class HikkakeModifiedAlgorithm : QCAlgorithm
{
private Symbol _symbol;
private HikkakeModified _hikkakemodified;
public override void Initialize()
{
_symbol = AddEquity("SPY", Resolution.Daily).Symbol;
_hikkakemodified = new HikkakeModified();
}
public override void OnData(Slice data)
{
if (data.Bars.TryGetValue(_symbol, out var bar))
{
_hikkakemodified.Update(bar);
}
if (_hikkakemodified.IsReady)
{
// The current value of _hikkakemodified is represented by itself (_hikkakemodified)
// or _hikkakemodified.Current.Value
Plot("HikkakeModified", "hikkakemodified", _hikkakemodified);
}
}
} class HikkakeModifiedAlgorithm(QCAlgorithm):
def initialize(self) -> None:
self._symbol = self.add_equity("SPY", Resolution.DAILY).symbol
self._hikkake_modified = HikkakeModified()
def on_data(self, slice: Slice) -> None:
bar = slice.bars.get(self._symbol)
if bar:
self._hikkake_modified.update(bar)
if self._hikkake_modified.is_ready:
# The current value of self._hikkake_modified is represented by self._hikkake_modified.current.value
self.plot("HikkakeModified", "hikkake_modified", self._hikkake_modified.current.value)
To register a manual indicator for automatic updates with the security data, call the RegisterIndicatorregister_indicator method.

Indicator History
To get the historical data of the HikkakeModified indicator, call the IndicatorHistoryself.indicator_history method.
This method resets your indicator, makes a history request, and updates the indicator with the historical data.
Just like with regular history requests, the IndicatorHistoryindicator_history method supports time periods based on a trailing number of bars, a trailing period of time, or a defined period of time.
If you don't provide a resolution argument, it defaults to match the resolution of the security subscription.
public class HikkakeModifiedAlgorithm : QCAlgorithm
{
private Symbol _symbol;
public override void Initialize()
{
_symbol = AddEquity("SPY", Resolution.Daily).Symbol;
var hikkakemodified = CandlestickPatterns.HikkakeModified(_symbol);
var countIndicatorHistory = IndicatorHistory(hikkakemodified, _symbol, 100, Resolution.Minute);
var timeSpanIndicatorHistory = IndicatorHistory(hikkakemodified, _symbol, TimeSpan.FromDays(10), Resolution.Minute);
var timePeriodIndicatorHistory = IndicatorHistory(hikkakemodified, _symbol, new DateTime(2024, 7, 1), new DateTime(2024, 7, 5), Resolution.Minute);
}
} class HikkakeModifiedAlgorithm(QCAlgorithm):
def initialize(self) -> None:
self._symbol = self.add_equity("SPY", Resolution.DAILY).symbol
hikkake_modified = self.CandlestickPatterns.hikkake_modified(self._symbol)
count_indicator_history = self.indicator_history(hikkake_modified, self._symbol, 100, Resolution.MINUTE)
timedelta_indicator_history = self.indicator_history(hikkake_modified, self._symbol, timedelta(days=10), Resolution.MINUTE)
time_period_indicator_history = self.indicator_history(hikkake_modified, self._symbol, datetime(2024, 7, 1), datetime(2024, 7, 5), Resolution.MINUTE)
To make the IndicatorHistoryindicator_history method update the indicator with an alternative price field instead of the close (or mid-price) of each bar, pass a selector argument.
var indicatorHistory = IndicatorHistory(hikkakemodified, 100, Resolution.Minute, (bar) => ((TradeBar)bar).High);
indicator_history = self.indicator_history(hikkake_modified, 100, Resolution.MINUTE, lambda bar: bar.high) indicator_history_df = indicator_history.data_frame
If you already have a list of Slice objects, you can pass them to the IndicatorHistoryindicator_history method to avoid the internal history request.
var history = History(_symbol, 100, Resolution.Minute); var historyIndicatorHistory = IndicatorHistory(hikkakemodified, history);
