stopLossPrice(sig, atr, factor, isLong)
Calculates the stop loss price using a distance determined by ATR multiplied by a factor. Example for Long trade SL: PRICE - (ATR * factor).
Parameters:
sig (float)
atr (float) : (float): The value of the atr.
factor (float)
isLong (bool) : (bool): The current trade direction.
Returns: (bool): A boolean value.
takeProfitPrice(sig, atr, factor, isLong)
Calculates the take profit price using a distance determined by ATR multiplied by a factor. Example for Long trade TP: PRICE + (ATR * factor). When take profit price is reached usually 50 % of the position is closed and the other 50 % get a trailing stop assigned.
Parameters:
sig (float)
atr (float) : (float): The value of the atr.
factor (float)
isLong (bool) : (bool): The current trade direction.
Returns: (bool): A boolean value.
trailingStopPrice(initialStopPrice, atr, factor, priceSource, isLong)
Calculates a trailing stop price using a distance determined by ATR multiplied by a factor. It takes an initial price and follows the price closely if it changes in a favourable way.
Parameters:
initialStopPrice (float) : (float): The initial stop price which, for consistency also should be ATR * factor behind price: e.g. Long trade: PRICE - (ATR * factor)

FVE - Finite Volume Elements [UTS]FVE is a money flow indicator but with two important differences from existing money flow indicators:
It resolves contradictions between intraday money flow indicators (such as Chaikin’s money flow) and interday money flow indicators (like On Balance Volume) by taking into account both intra- and interday price action.
Unlike other money flow indicators which add or subtract all volume even if the security closed just 1 cent higher than the previous close, FVE uses a volatility threshold to take into account minimal price changes.
General Usage
The FVE provides 3 types of signals:
The strongest signal is divergence between price and the indicator. Divergence can provide leading signals of breakouts or warnings of impending corrections. The classic method for detecting divergence is for FVE to make lower highs while price makes higher highs (negative divergence). An alternative method is to draw the linear regression line on both charts, and compare the slopes. A logical buy signal would be for FVE, diverging from price, to rise sharply and make a series higher highs and/or higher lows.
The most obvious and coincident signal is the slope of the FVE line. An upward slope indicates that the bulls are in control and the opposite for downward.
This is a unique and very important property of this indicator. Values above zero are bullish and indicate accumulation while values below zero indicate distribution. FVE crossing the zero line indicates that the short to intermediate balance of power is changing from the bulls to the bears or vice versa. The best scenario is when a stock is in the process of building a base, and FVE diverges from price and rises to cross the zero line from below, at a sharp angle. Conversely the crossing of the zero line from above is a bearish signal to liquidate positions or initiate a short trade.
Trend Visualisation
Optional: If the trend direction is DOWN the moving average is painted red. If the trend direction is UP the moving average is painted in green.
If the movement is FLAT then the color is grey.
Moving Averages
Five different types of Moving Averages are available for both FVE and the optional moving average of the FVE.
ALMA (Arnaud Legoux Moving Average)
Average Value
EMA (Exponential Moving Average)
SMA (Simple Moving Average)
WMA (Weighted Moving Average)
Calculation Methods
Since Markos Katsanos presented the first version of the FVE in April 2003.
Since then there have been various adaptions and improvements on this indicator.
The following are choosable for calculating the FVE:

VFI - Volume Flow Indicator [UTS]The Volume Flow Indicator (VFI) indicator was first introduced in my June 2004 and is is based on the popular On Balance Volume (OBV) but with three very important modifications:
Unlike the OBV, indicator values are no longer meaningless. Positive readings are bullish and negative bearish.
The calculation is based on the day's median instead of the closing price.
A volatility threshold takes into account minimal price changes and another threshold eliminates excessive volume.
The indicator takes into account only the latest 6 month volume action and not the entire data loaded in the chart.
General Usage
A simplified interpretation of the VFI is that values above zero indicate a bullish state and the crossing of the zero line is the trigger or buy signal.
The strongest signal with all money flow indicators is of course divergence.
The classic form of divergence is when the indicator refuses to follow the price action and makes lower highs while price makes higher highs (negative divergence). If price reaches a new low but the indicator fails to do so, then price probably traveled lower than it should have. In this instance, you have positive divergence.

CMF Osc - Chaikin Money Flow Oscillator [UTS]The well known Chaikin Money Flow Indicator as oscillator version.
General Usage
The indicator runs both above and below zero, made to denote whether an asset is in a bullish (above zero) or bearish (below zero) trend.
It can be used to confirm trends, as well as spot possible trading signals due to divergences.
A benefit of the oscillator version is that it can produce LONG or SHORT signals on zero line cross.
Moving Averages
4 different Moving Averages are available:
EMA (Exponential Moving Average)
SMA (Simple Moving Average)
VWMA (Volume Weighted Moving Average)
WMA (Weighted Moving Average)
Chaikin Oscillator (ADL Oscillator) [UTS]The Chaikin Oscillator is basically an oscillator version of the Accumulation / Distribution Index, also known as ADL Indicator.
General Usage
The indicator runs both above and below zero, made to denote whether an asset is in a bullish (above zero) or bearish (below zero) trend.
It can be used to confirm trends, as well as spot possible trading signals due to divergences.
A benefit of the oscillator version is that it can produce LONG or SHORT signals on zero line cross.
Moving Averages
4 different Moving Averages are available:
EMA (Exponential Moving Average)
SMA (Simple Moving Average)
VWMA (Volume Weighted Moving Average)
WMA (Weighted Moving Average)
PVT Osc - Price Volume Trend Oscillator [UTS]The oscillator version of the Price Volume Trend indicator (PVT) can be considered as a leading indicator of future price movements. The PVT Indicator is similar to the On Balance Volume indicator as it is also used to measure the strength of a trend.
The difference between the OBV and the PVT is that where the OBV adds all volumes when price achieves higher daily closes and subtracts them when price registers a lower daily close, the PVT adds or subtracts only a portion of the volume from the cumulative total in relation to a percentage change in price.
The general market consensus is that this difference enables the PVT to more accurately represent money flow volumes in and out of a stock or commodity.
The PVT has been designed so that it is capable of forecasting directional changes in price. For instance, if the price of a stock is rising and the PVT begins to fall, then this is indicative that a price reversal could occur very soon.
The general consensus is that the PVT is more accurate at detecting new trading opportunities than the OBV because of the differences in their construction. The OBV is designed so that it adds the same amount of volume whether the price closes upwards by just a small fraction or by multiples of its day opening value. On the other hand, the PVT adds volume proportional to the amount the price closed higher.
General Usage
Plain old PVT can be used to confirm trends, as well as spot possible trading signals due to divergences.
A benefit of the oscillator version is that it can produce LONG or SHORT signals on zero line cross.
Or controversy, disallow LONG trades in bearish territory and disallow SHORT trades in bullish territory.
Moving Averages

EMA (Exponential Moving Average)
SMA (Simple Moving Average)
VWMA (Volume Weighted Moving Average)

MFI - Money Flow Index [UTS]Money Flow Index (MFI) is the technical indicator, which indicates the rate at which money is invested into a security and then withdrawn from it.
Construction and interpretation of the indicator is similar to Relative Strength Index with the only difference that volume is important to MFI.
Usage:
When analyzing the money flow index one needs to take into consideration the following points:
divergences between the indicator and price movement. If prices grow while MFI falls (or vice versa), there is a great probability of a price turn;
Money Flow Index value, which is over 80 or under 20, signals correspondingly of a potential peak or bottom of the market.
Common known variants of this type of indicator are the On Balance Volume, Chaikin Oscillator or Chaikin Money Flow.
