[FTA] Curvature of MeniscusIntroduction:
Curvature of Meniscus is a hybrid indicator comprised of three parts:
1. The first part is a heavily modified Demarker RSI which is represented as the histogram and is the main trend indicator C1 .
2. The second part is the 0 line which is replaced by the Waddah Attar Explosion V2 indicator C2 .
3. The third part is the background color which is borrowed from the Klinger Safety Zones volume indicator Vol .
It is smooth and has almost zero lag.
The signals can be used as per nnfx C1-C2-Vol algorithm.
The DeMarker indicator is relatively unknown to trading beginners but enjoys huge support from the more experienced traders. The indicator measures the strength of a trend and thus can give you a warning when a change in the trend direction might occur. This can not only help you to find new trade entries but also prevent you from entering into losing trades or letting your open trades run and ultimately result in a loss.
The line of the indicator is calculated as follows: First the indicator finds the minimal and the maximal value of the specified period. Afterwards those values are used to calculate the moving average of these values which then is displayed in the chart. Just like most oscillators the DeMarker indicator uses oversold and overbought zones at 0.3 and 0.7 to define good entry opportunities.
The "Curvature of Meniscus" indicator has the DeMarker indicator/RSI modified in three different ways:
1. Smoothed and almost no-lagged;
2. Colored histogram to determine the trend and the divergences;
3. An early signal line for those who like to take counter-trend trades/reversal entries.

█ OVERVIEW
This library holds technical analysis functions calculating values for which no Pine built-in exists.
Look first. Then leap.
█ FUNCTIONS
cagr(entryTime, entryPrice, exitTime, exitPrice)
It calculates the "Compound Annual Growth Rate" between two points in time. The CAGR is a notional, annualized growth rate that assumes all profits are reinvested. It only takes into account the prices of the two end points — not drawdowns, so it does not calculate risk. It can be used as a yardstick to compare the performance of two instruments. Because it annualizes values, the function requires a minimum of one day between the two end points (annualizing returns over smaller periods of times doesn't produce very meaningful figures).
Parameters:
entryTime : The starting timestamp.
entryPrice : The starting point's price.
exitTime : The ending timestamp.
exitPrice : The ending point's price.
Returns: CAGR in % (50 is 50%). Returns `na` if there is not >=1D between `entryTime` and `exitTime`, or until the two time points have not been reached by the script.
█ v2, Mar. 8, 2022

Reversal Points [CC]This original script was created based on a suggestion from @kerpiciwuasile. My original Reversal Points script was removed because I modeled it after an indicator by Demark, but this script will have no such issues. Reversal points are an exciting concept for me because it is such a useful tool when placing trades. This is my first attempt at a new overall layout for my script and I included a bunch of customization so let me know what you think.
My script works by finding lows that are surrounded by bars that have higher lows and highs that are surrounded by lower highs. I use this logic to find short term lows or highs and I use the same concept to find mid-term lows or highs but a mid-term high is a short term high surrounded by lower short term highs and a mid-term low is a short term low surrounded by higher short term lows. And of course this means that long term highs or lows use the same logic to find highs or lows that are surrounded by mid-term highs or lows. I would recommend to buy at the long term low points or sell at the long term high points.
Keep in mind of course that short term highs and lows are very common and reversal points will get rarer as you look for longer term reversal points. I would recommend to experiment and see which reversal points work best for you and of course, know that there is no magical formula to use for all stocks.
Also there are a few scenarios where you want to enable or disable the inside bar setting. You would want to ignore inside bars if the market is currently very volatile or if you are using this indicator on a crypto chart. This is not an exact science but more of a recommendation, so feel free to experiment with it.
Reversal points are crucial for traders as they signal a potential change in the market trend, providing opportunities for entry or exit.
In summary, this code snippet is a powerful tool for traders to detect and visualize reversal points on a trading chart, providing valuable insights into potential trend changes and facilitating more informed trading decisions.
Let me know if you would like me to publish other scripts or if you want me to do something custom for you!
Fuzzy Fib CountsA new approach to trend/time analysis. This indicator counts up/down price moves using fuzzy logic in two time frames. Counts reaching Fibonacci numbers are often significant to trend momentum: either reversal or stronger continuation. See the script’s beginning comments for details.
I’m amazed with DeMark and all his indicators. But after coding a TD_Sequential script, I began to wonder if there wasn’t an easier way to identify high probability entry/exit points without all the intricate logic. It took awhile, but a different paradigm eventually came into focus: Fuzzy Fib Counts (FFC).
FFC is like “analog” compared to TD_Sequential’s “digital” approach. And FFC is much simpler: no buy/sell/perfected/deferred signals, just up/down counts. It’s uncanny how often a trend is refocused at Fibonacci numbers, but like TD_Sequential… it’s not perfect! As with all indicators, consult your intuition, before pulling the trigger.
The default values have been effective for me in Bitcoin (and I’m surprised how well it works in smaller time frames). However, for less volatile markets, you may need to reduce the fuzz level and/or adjust the filter (averaging) parameters.
FFC has been helpful to me. Hope it helps you too! If so, donations appreciated… Thanks!
