Branch CurveLibrary "branch"
Generates a branch made of segments with a starting angle
and a turning angle for each segment. The branch is generated from a starting point
and a number of nodes to generate. The length of each segment and angle of each segment
can be adjusted. The branch can be generated in 2D or 3D, render as you wish.
method branch(origin, nodes, segment_length, segment_growth, angle_start, angle_turn)
# Branch Generation.

Bitwise, Encode, Decode Docs
In the documentation you may notice the word decimal
not used as normal this is because when referring to
binary a decimal number is a number that
can be represented with base 10 numbers 0-9
(the wiki below explains better)
A rule of thumb for the two integers being
encoded it to keep both numbers
less than 65535 this is because anything lower uses 16 bits or less
this will maintain 100% accuracy when decoding
although it is possible to do numbers up to 2147483645 with
this library doesnt seem useful enough
to explain or demonstrate.
The functions provided work within this 32-bit range,
where the highest number is all 1s and
the lowest number is all 0s. These functions were created
to overcome the lack of built-in bitwise functions in Pinescript.
By combining two integers into a single number,
the code can access both values i.e when
indexing only one array index
for a matrices row/column, thus improving execution time.
This technique can be applied to various coding
scenarios to enhance performance.
Bitwise functions are a way to use integers in binary form
that can be used to speed up several different processes
most languages have operators to perform these function such as
`<<, >>, &, ^, |, ~`

L_Trade_BoundariesLibrary "L_Trade_Boundaries"
Trade Boundaries suggest a strength of the security with respect to previous lows. The "L" implies library, and the trade boundaries implies it could be utilized for price strengths. Though, this should not be used as a single parameter to trade wildly. This library can be imported to a custom indicator to utilized the custom functions. There are moving averages attached at the bottom right of the canvas (overlay) to benchmark the closing price with respect to Moving Averages: 20, 28, and 200 (i.e., "D" if timeframe == "D") respectively. The Volume Indicator located at the top of the canvas is a default function (function already made by the trading view) this shows the volume with respect to the selected time frame. All of the indicators tell a story with regard to the security price (in strength terms).
What is available in this Library?
Litmus Color
> This is a function will change color of two numbers, if the first number is less than the second, the color will be red; otherwise, the color will be green.
Lister
> This is simply using an array by revisiting previous lows and plotting to the current time frame (i.e., "D"). There is a custom frequency input for the function, it will go back as much as the implied/specified length. Note: I am still learning how to use array, use this function with discretion. I would also appreciate if there are suggestions commented below.
Moving Average
> This function invokes three moving average metrics: 20, 28, and 200 respectively. The values are displayed at the bottom right of the canvas.
Timeframe Highlight
> This function checks for the input timeframe (i.e., "D", "W", "M") and if the time frame happens to be the same, it will give a "true" result. This result can be utilized for highlighting the positive results on the canvas (the red lines).

store - larger data storage for complex item typesLibrary "store"
Object/Property Storage System Semi-Simplified. .
It's a helpful toolset while designing UDT's as it remains flexible,
this helps in not having to remap an entire script while tinkering.
Set an object up, and add as man properties as yyou wish.
a property can be one of any pine built in types. so a single
object can contain sa, ohlc each with a color, a float, an assigned int
and those 4 props each have 3 sub-assigned values.
as in demo, the alternating table object has 2 different tables
it's a pseudo more complex wa to create our own flexible
version of a UDT, but that will not ~break~ on library updates
so you can update awa without fear, as this libb will no change
saving ou the hassle of creating UDT's that continually change.

keyed value types with pseudo-dict - Methods Library "key_vals"
a set of primitive single-type key/value items, and pseudo-dictionaries
The dictionaries are single arrays of items, each item has a key and value.
The library is 100% methods. add, remove, get and set items by key.
It provides methods to get all the keys, values or items in the dict as arrays.
For those familiar with python, it's similar, but typified.. and the brackets are round.
example syntax.. using floats, the same functions exist for Int, Bool and String
new float_item
new (‘demo’, 1.0 )
set the key of a float_item
float_item.key (‘demo’)
get the key of a float_item
float_item.key ()
set the value of a float_item
float_item.val (1.5)
get the value of a float_item
float_item.val ()
get the number of items in a dict
float_dict.count ()
set an item to a dict by key ( add / update)
float_dict.set ( ‘demo’, 2.0 )
remove an item from a dict by key (changes index, but this is about keys, not ids)
float_dict.remove ( ‘demo’ )
get an item from a dict array
array.get (1 )
get an item from a dict by key
float_dict.get ( ‘demo’ )
get an item from a dict by id (remember, ids change if removed by key) mainlyy an internal function
float_dict.get ( 1)
return all keys as string
float_dict.get_keys()
return all values as float
float_dict.get_values()
return all items as float
float_dict.get_items()
create a new float dict in the multi dict and return the index of it
multi_dict.add_float_dict()
get the float dict at index 0 from the multi dict
multi_dict.get_float_dict( 0)
set an item in a float dict in a multi dict
multi_dict.set_float( ‘demo’, 2.0 )
get an item from a float dict in a multi dict
multi_dict.get_float( ‘demo’ )

Replica of TradingView's Backtesting Engine with ArraysHello everyone,
Here is a perfectly replicated TradingView backtesting engine condensed into a single library function calculated with arrays. It includes TradingView's calculations for Net profit, Total Trades, Percent of Trades Profitable, Profit Factor, Max Drawdown (absolute and percent), and Average Trade (absolute and percent). Here's how TradingView defines each aspect of its backtesting system:
Net Profit: The overall profit or loss achieved.
Total Trades: The total number of closed trades, winning and losing.
Percent Profitable: The percentage of winning trades, the number of winning trades divided by the total number of closed trades.
Profit Factor: The amount of money the strategy made for every unit of money it lost, gross profits divided by gross losses.
Max Drawdown: The greatest loss drawdown, i.e., the greatest possible loss the strategy had compared to its highest profits.
Average Trade: The sum of money gained or lost by the average trade, Net Profit divided by the overall number of closed trades.
Here's how each variable is defined in the library function:
_backtest(bool _enter, bool _exit, float _startQty, float _tradeQty)
bool _enter: When the strategy should enter a trade (entry condition)
bool _exit: When the strategy should exit a trade (exit condition)
float _startQty: The starting capital in the account (for BTCUSD, it is the amount of USD the account starts with)
float _tradeQty: The amount of capital traded (if set to 1000 on BTCUSD, it will trade 1000 USD on each trade)
Currently, this library only works with long strategies, and I've included a commented out section under DEMO STRATEGY where you can replicate my results with TradingView's backtesting engine. There's tons I could do with this beyond what is shown, but this was a project I worked on back in June of 2022 before getting burned out. Feel free to comment with any suggestions or bugs, and I'll try to add or fix them all soon. Here's my list of thing to add to the library currently (may not all be added):
Add commission calculations.
Add support for shorting
Add a graph that resembles TradingView's overview graph.
Clean and optimize code.
Clean up in a way that makes it easy to add other TradingView calculations (such as Sharpe and Sortino ratio).
Separate all variables, so they become accessible outside of calculations (such as gross profit, gross loss, number of winning trades, number of losing trades, etc.).
Thanks for reading,
