TimezoneFormatIANAUTC Library "TimezoneFormatIANAUTC" Provides either the full IANA timezone identifier or the corresponding UTC offset for TradingView’s built-in variables and functions. tz(_tzname, _format) Parameters: _tzname (string) : "London", "New York", "Istanbul", "+1:00", "-03:00" etc. _format (string) : "IANA" or "UTC" Returns: "Europe/London", "America/New York", "UTC+1:00" Example Code import ARrowofTime/TimezoneFormatIANAUTC/1 as libtz sesTZInput = input.string(defval = "Singapore", title = "Timezone") example1 = libtz.tz("London", "IANA") // Return Europe/London example2 = libtz.tz("London", "UTC") // Return UTC+1:00 example3 = libtz.tz("UTC+5", "IANA") // Return UTC+5:00 example4 = libtz.tz("UTC+4:30", "UTC") // Return UTC+4:30 example5 = libtz.tz(sesTZInput, "IANA") // Return Asia/Singapore example6 = libtz.tz(sesTZInput, "UTC") // Return UTC+8:00 sesTime1 = time("","1300-1700", example1) // returns the UNIX time of the current bar in session time or na sesTime2 = time("","1300-1700", example2) // returns the UNIX time of the current bar in session time or na sesTime3 = time("","1300-1700", example3) // returns the UNIX time of the current bar in session time or na sesTime4 = time("","1300-1700", example4) // returns the UNIX time of the current bar in session time or na sesTime5 = time("","1300-1700", example5) // returns the UNIX time of the current bar in session time or na sesTime6 = time("","1300-1700", example6) // returns the UNIX time of the current bar in session time or na Parameter Format Guide This section explains how to properly format the parameters for the tz(_tzname, _format) function. _tzname (string) must be either; A valid timezone name exactly as it appears in the chart’s lower-right corner (e.g. New York, London). A valid UTC offset in ±H:MM or ±HH:MM format. Hours: 0–14 (zero-padded or not, e.g. +1:30, +01:30, -0:00). Minutes: Must be 00, 15, 30, or 45 examples; "New York" → ✅ Valid chart label "London" → ✅ Valid chart label "Berlin" → ✅ Valid chart label "America/New York" → ❌ Invalid chart label. (Use "New York" instead) "+1:30" → ✅ Valid offset with single-digit hour "+01:30" → ✅ Valid offset with zero-padded hour "-05:00" → ✅ Valid negative offset "-0:00" → ✅ Valid zero offset "+1:1" → ❌ Invalid (minute must be 00, 15, 30, or 45) "+2:50" → ❌ Invalid (minute must be 00, 15, 30, or 45) "+15:00" → ❌ Invalid (hour must be 14 or below) _tztype (string) must be either; "IANA" → returns full IANA timezone identifier (e.g. "Europe/London"). When a time function call uses an IANA time zone identifier for its timezone argument, its calculations adjust automatically for historical and future changes to the specified region’s observed time, such as daylight saving time (DST) and updates to time zone boundaries, instead of using a fixed offset from UTC. "UTC" → returns UTC offset string (e.g. "UTC+01:00")

Volume [Educational]Hello All, This is an educational work and it's developed to show how to write scripts that will work like built-in volume indicator. We have new features in Pine Script™ Language, such chart.bg_color, chart.fg_color, chart.left_visible_bar_time, chart.right_visible_bar_time and many more. Many Thanks to Tradingview and Pine Team for such great additions! You can find more information about these new functions here . How the script works? - At the first step it calculates how many visible bar on the chart by using chart.right_visible_bar_time and chart.left_visible_bar_time functions. - Calculates the zero line for the volume - Finds maximum volume on visible area and normalize all volume values - Draws volume bars - Shows volume info as indicator value. in this step it uses chart.fg_color and plotarrow() commands to show the values in optimum color. In order to place the indicator at the bottom of the chart, Please set Bottom Margin = 0 as shown in the following screenshot: You can change the volume bar colors optionally. An Example screenshot with different volume bar colors: Enjoy!

Learning Built-in Vars I'm currently working on v5 of my Pine Script Programming Course. As a part of it, I'm building a few tools/widgets to help students get the content easier. Here is one of the tools. It's quite basic with it you can select a bar and see all the build-in variables for this bar (Except strategy variables) I hope it will help you in learning Pine Script! Disclaimer Please remember that past performance may not be indicative of future results. Due to various factors, including changing market conditions, the strategy may no longer perform as well as in historical backtesting. This post and the script don’t provide any financial advice.

GMS: GW-VWAP Alright, as per usual with these, I end up adapting an existing indicator to what I want to accomplish. So this is based off the built in VWAP indicator. I added in the gummy worm to easily identify the trend, as well as the related bands to identify potential areas to either reverse position or to trim an existing one. The middle part of the bands are the gummy worm version of VWAP. It is the VWAP using the high and another VWAP using the low. The black line is HL2 VWAP (technically 3 VWAPs). The bands follow what I was mentioning above. So the outer most part of the bands are the high & low VWAP (with the same multiplier) and the inner bands are the HL2 VWAP. Of course you can set whatever input source you want for these. The default is how I use it. If you want to get rid of the bar color just go to the indicator settings and un-select it at the bottom. Source code is open so feel free to poke around. Hope this helps, Andre

Bollinger Band Color Bars This is a simple addition to the built in Bollinger Bands script. All it does is replaces the traditional plotting of Bollinger Bands with color bars.

Combined Candlestick Patterns I combined all the build-in candlestick patterns scripts into one single script so anyone who does not have a Pro plan can display all the patterns in the same chart. Leave a comment for any feedback!

[RESEARCH] Mean Absolute Deviation Hello traders and developers! I was wondering how built-in "dev" function in Pine is calculated so I made a little research. I examined 7 samples: 0) "dev" function itself 1) "dev" according to its description: series - sma(series) 2) Mean Absolute Deviation 3) ratio of the absolute difference from 1) divided by period 4) ratio of the difference from 1) divided by period 5) Median Absolute Deviation 6) tricky for-loop to calculate Mean Absolute Deviation The results of the null and sixth samples are identical. So, TV built-in "dev" function represents Mean Absolute Deviation and it's description is incorrect. Where it is used? For example: Commodity Channel Index. You can check its original formula and if you used simple standard deviation instead of MAD in your CCIs - well guys, you were wrong. Good luck!

[RESEARCH] Rate of Change Hello traders and developers! I was wondering how built-in "roc" function in Pine is defined and calculated so I made a little research. I examined 4 samples: 1) "roc" function itself 2) "roc" according to its description 3) price change ratio 4) price percent change ratio The results of the first and fourth samples are identical. So, TV built-in roc(source, length) = 100 * change(source, length) / source . And it's description is incorrect. If you didnt know it - now you know it. Good luck!
