OPEN-SOURCE SCRIPT
Scalp Tool
Updated
https://www.tradingview.com/x/RsHbdLR3/
This script is primarily intended as a scalping tool.
The theory of the tool is based on the fact that the price always returns to its mean.
Elements used:
1. VWMA as a moving average. VWMA is calculated once based on source close and once based on source open.
2. the bands are not calculated like the Bollinger Band, but only a settlement is calculated for the lower bands based on the Lows and for the upper bands based on the Highs. Thus the bands do not become thicker or thinner, but remain in the same measure to the mean value above or below the price.
3. a volume filter on simple calculation of a MA with deviation. Therefore, it can be identified if a volume breakout has occurred.
4. support and resistance zones which are calculated based on the highs and lows over a certain length.
5. RSI to determine oversold and overbought zones. It also tries to capture the momentum by using a moving average (variable selectable) to filter the signals. The theory is that in an uptrend the RSI does not go below 50 and in a downtrend it does not go above 50.
However, this can be very different depending on the financial instrument.
Explanation of the signals:
The main signal in this indicator Serves for pure short-term trading and is generated purely on the basis of the bands and the RSI.
Only the first bands are taken into account.
Buy signal is generated when the price opens below the lower band 1 and closes above the lower band 1 or the RSI crosses a value of 25 from bottom to top.
Sell signal is generated when the price opens above the Upper Band 1 and closes below the Upper Band 1 or the RSI crosses a value of 75 from top to bottom.
The position should be closed when the price hits the opposite band. Alternatively, it can also be closed at the mean.
Other side signals:
1. breakouts:
The indicator includes 2 support and resistance zones, which differ only in length. For the breakout signals, the short version of the R/S is used. A signal is generated when the price breaks through the zones with increased volume. It is then assumed that the price will continue to follow the breakout.
The values of the S/R are adjustable and marked with "BK".
The value under Threshold 2 defines the volume breakout. 4 is considered as the highest value. The smaller the value, the smaller the volume must be during a breakout.
2. bounce
If the price hits a S/R (here the long variant is used with the designation "Support" or "Resistance") and makes a wick with small volume, the script assumes a bounce and generates a Sell or Buy signal accordingly.
The volume can be defined under "Threshold".
The S/R according to the designation as well.
Combined signals:
If the value of the S/R BK and the S/R is the same and the bounce logic of the S/R BK applies and an RSI signal is also generated, a signal is also plotted.
Here the idea was to get very strong signals for possible swing entries.
4. RSI Signals
The script contains two RSI.
RSI 1:
Bullish signal is generated when the set value is crossed from the bottom to the top.
Bearish signal is generated when the set value is crossed from the top to the bottom.
RSI 2:
Bullish signal is generated when the set value is crossed from the top to the bottom.
Bearish signal is generated when the set value is crossed from bottom to top.
For RSI 2 the theory is taken into account according to the description under Used elements point 5
Optical trend filter:
Also an optical trend filter was generated which fills the bands accordingly.
For this the VWMA is used and the two average values of the band.
Color definition:
Gray = Neutral
Red = Bearish
Green = Bullish
If the mean value is above the VWMA and the mean value based on the closing price is above the mean value based on the open price, the band is colored green. It is a bullish trend
If the mean value is below the VWMA and the mean value based on the closing price is below the mean value based on the open price, the band is colored red.
The band is colored gray if the mean value is correspondingly opposite. A sideways phase is assumed.
The script was developed on the basis of the pair BTCUSD in the 15 minute chart and the settings were defined accordingly on it. The display of S/R for forex pairs does not work correctly and should be hidden. The logic works anyway.
When using the script, all options should first be set accordingly to the asset and tested before trading afterwards. It applies of course also here that there is no 100% guarantee.
Also, a strong breakout leads to false signals and overheating of the indicator.

Release Notes
The calculation for the bands has been changed so that the ratio of the center to the upper and lower bands remains the same even if the timeframe is changed.Release Notes
New functions:The Support and Resistance Zone is now also displayed as a zone. The area between Highest Close and Highest High as well as the area between Lowest Close and Lowest Low of the set period are marked.
The candles can now be colored on the basis of the RSI.
5 zones have been defined
Extreme Upper = RSI above 70
Upper = RSI above 55 but below 70
Middle = RSI between 45 and 55
Lower = RSI below 45 but above 30
Extreme Lower = RSI below 30
The theory
If the RSI is above 55, one assumes a bullish momentum.
An RSI above 70 is considered overbought and a market reversal is expected. However, there are also theories which say that a value above 70 speaks for an extreme bullish momentum.
Values between 45 and 55 are considered neutral (I prefer values between 47 and 53).
Values below 45 but above 30 indicate a bearish momentum.
Values below 30 indicate an oversold market and a reversal is expected. However, the opposite can also be considered here and an extremely bearish momentum can be assumed.
The values as well as bar colors are freely adjustable.
Release Notes
Small change to the Devault settings and update of the chart imageRelease Notes
An error in the signal display has been corrected.Now the signals can be activated or deactivated directly in the settings. Since certain signals arise when a combination of other signals occurs, the deactivation of higher-level signals led to the fact that nothing was displayed. With the correction the signals are displayed if a higher prioritized signal is deactivated. The checkboxes were listed in the prioritization order. Top checkbox has Prio 5 Bottom = Prio 1
