Extrapolated Pivot Connector - Lets Make Support And ResistancesIntroduction The support and resistance methodology remain the most used one in technical analysis, this is mainly due to its simplicity, and unlike lots of techniques used in technical analysis support and resistances have a certain logic, price can sometimes appear moving into a channel, support and resistances allow the trader to estimate such channel and project it into the future in order to spot points where price might reverse direction. In this script a simple linear support and resistance indicator is proposed, the indicator is made by connecting past pivot high's/low's to more recent ones and extrapolating the resulting connection. The indicator is also able to make support and resistances by using other indicators as input. Indicator Settings The indicator include various settings, the first one being the length setting who determine the sensitivity of the pivot high/low detection, low values of length will detect the pivot high/low of noisy variations, while higher values will detect the pivot high/low of longer term variations. The figure above use length = 5. The A-High parameter determine the position of the pivot high to be used as first point of the resistance line, higher values will use oldest pivot high's as first point. The B-High parameter determine the last pivot high. A-Low and B-Low work the same way but affect the support line, a label is drawn on the chart in order to help you determine the position of A/B-High/Low. Using Other Indicators Output As Input The "Use Custom Source" option allow you to apply the indicator to other indicators, for example we can use a moving average of period 50 as input Or the rsi : Let me help you set the proposed indicator easily to indicators appearing on a separate window, for example the momentum oscillator, add the momentum oscillator to the chart, to do so click on indicator and search "momentum", click on the first result, once on the chart put your mouse pointer on the indicator title, you'll see appearing the hide, settings and delete option, at the right of delete you should see three dots which represent the "more" option, click on it and select "Add indicator on Mom" and select the extrapolated pivot indicator, you can do that by searching it, altho it might be easier to do it by adding the indicator to favorites first, you then only need to select it from your favorites. You might see a mess on the indicator window, thats because the extrapolated pivot is still using high and low as input, go to the settings of the extrapolated pivot indicator and check "Use Custom Source", it should appear properly now. Tips And Tricks When Using Support And Resistances Linear support and resistances assume an approximately linear trend, if you see non linear growth in the price evolution you can use a logarithmic scale in order to have a more linear evolution. To do so right click on the the chart scale and select "Logarithmic" or use the following key shortcut "alt + l". When applying the indicator to an oscillator centered around zero make sure to adjust the settings of the oscillator such that the peak magnitude of the oscillator is relatively constant over time. Here a roc of period 9 has non constant peak amplitude, you can see that by looking at the position of the pivots (circles), increasing the period of the roc help capture more significant pivots high's/low's Conclusion In this post an indicator aiming to draw support and resistances is presented, the fact that it can be applied to any other indicator is a relatively nice option, and i hope you might make use of this feature. The code make heavy use of the new features that where integrated on the v4 of pine, such features are really focused on making figures and labels, things i don't really work with, but it is nice to step out my short codes habits, and i don't exclude working with figures in pine in the future.

LSMA - A Fast And Simple Alternative CalculationIntroduction At the start of 2019 i published my first post "Approximating A Least Square Moving Average In Pine", who aimed to provide alternatives calculation of the least squares moving average (LSMA), a moving average who aim to estimate the underlying trend in the price without excessive lag. The LSMA has the form of a linear regression ax + b where x is a linear sequence 1.2.3..N and with time varying a and b , the exact formula of the LSMA is as follows : a = stdev(close,length)/stdev(bar_index,length) * correlation(close,bar_index,length) b = sma(close,length) - a*sma(bar_index,length) lsma = a*bar_index + b Such calculation allow to forecast future values however such forecast is rarely accurate and the LSMA is mostly used as a smoother. In this post an alternative calculation is proposed, such calculation is incredibly simple and allow for an extremely efficient computation of the LSMA. Rationale The LSMA is a FIR low-pass filter with the following impulse response : The impulse response of a FIR filter gives us the weight of the filter, as we can see the weights of the LSMA are a linearly decreasing sequence of values, however unlike the linearly weighted moving average (WMA) the weights of the LSMA take on negative values, this is necessary in order to provide a better fit to the data. Based on such impulse response we know that the WMA can help calculate the LSMA, since both have weights representing a linearly decreasing sequence of values, however the WMA doesn't have negative weights, so the process here is to fit the WMA impulse response to the impulse response of the LSMA. Based on such negative values we know that we must subtract the impulse response of the WMA by a constant value and multiply the result, such constant value can be given by the impulse response of a simple moving average, we must now make sure that the impulse response of the WMA and SMA cross at a precise point, the point where the impulse response of the LSMA is equal to 0. We can see that 3WMA and 2SMA are equal at a certain point, and that the impulse response of the LSMA is equal to 0 at that point, if we proceed to subtraction we obtain : Therefore : LSMA = 3WMA - 2SMA = WMA + 2(WMA - SMA) Comparison On a graph the difference isn't visible, subtracting the proposed calculation with a regular LSMA of the same period gives : the error is 0.0000000...and certainly go on even further, therefore we can assume that the error is due to rounding errors. Conclusion This post provided a different calculation of the LSMA, it is shown that the LSMA can be made from the linear combination of a WMA and a SMA : 3WMA + -2SMA. I encourage peoples to use impulse responses in order to estimate other moving averages, since some are extremely heavy to compute. Thanks for reading !

Optimized Trend TrackerA brand new indicator from the developer of MOST (Moving Stop Loss) indicator Anıl Özekşi. Optimized Trend Tracker OTT is an indicator that provides traders to find an existing trend or in another words to ser which side of the current trend we are on. We are under the effect of the uptrend in cases where the prices are above OTT , under the influence of a downward trend, when prices are below OTT it is possible to say that we are. The first parameter in the OTT indicator set by the two parameters is the period/length. OTT will be much sensitive to trend movements if it is smaller. And vice versa, will be less sensitive when it is longer. As the period increases it will become less sensitive to little trends and price actions. In this way, your choice of period, will be closely related to which of the sort of trends you are interested in. The OTT percent parameter in OTT is an optimization coefficient. Just like in the period small values ​​are better at capturing short term fluctuations, while large values will be more suitable for long-term trends. In addition, when OTT is used with the support line in it, buy and sell signals it will become a producing indicator. You can use OTT default alarms and Buy Sell signals like: 1- BUY when Prices are above OTT SELL when Prices are below OTT 2- BUY when OTT support Line crosses over OTT line. SELL when OTT support Line crosses under OTT line. 3- BUY when OTT line is Green and makes higher highs. SELL when OTT line is Red and makes lower lows. Note: A small coverage with English subtitles will be available on my Youtube Channel soon.

Average Sentiment OscillatorDescription of this indicator from its author: Average Sentiment Oscillator Momentum oscillator of averaged bull/bear percentages. We suggest using it as a relatively accurate way to gauge the sentiment of a given period of candles, as a trend filter or for entry/exit signals. It’s a combination of two algorithms, both essentially the same but applied in a different way. The first one analyzes the bullish/bearishness of each bar using OHLC prices then averages all percentages in the period group of bars (eg. 10) to give the final % value. The second one treats the period group of bars as one bar and then determines the sentiment percentage with the OHLC points of the group. The first one is noisy but more accurate in respect to intra-bar sentiment, whereas the second gives a smoother result and adds more weight to the range of price movement. They can be used separately as Mode 1 and Mode 2 in the indicator settings, or combined as Mode 0. Original indicator idea from Benjamin Joshua Nash, converted from MT4 version Usage: The blue line is Bulls %, red line is Bears %. As they are both percentages of 100, they mirror each other. The higher line is the dominating sentiment. The lines crossing the 50% centreline mark the shift of power between bulls and bears, and this often provides a good entry or exit signal, i.e. if the blue line closes above 50% on the last bar, Buy or exit Sell, if the red line closes above 50% on the last bar, Sell or exit Buy. These entries are better when average volume is high. It's also possible to see the relative strength of the swings/trend, i.e. a blue peak is higher than the preceding red one. A clear divergence can be seen in the picture as the second bullish peak registers as a lower strength on the oscillator but moved higher on the price chart. By setting up levels at the 70% and 30% mark the oscillator can also be used for trading overbought/oversold levels similar to a Stochastic or RSI. As is the rule with most indicators, a smaller period gives more leading signals and a larger period gives less false signals.
