Tick Volume Direction IndicatorTick Volume Direction Indicator
This indicator captures:
• tick volume
• tick direction
The settings are as follows:
• volume or base currency value selection.
• label distance (away from the low of the candle).
• Tick volume - on/off switch for tick volume.
• label size.
• Up tick move color.
• tick move absorbed - when the tick doesn't change position.
• Down tick move.
On the first initial load, it will have the existing volume data as "?" as tradingview doesn't have a history of each tick.
Be aware, any settings change you make will refresh the tick data from start.
This indicator is one of the best real-time ways of seeing buying and selling pressure.
List
Data structure ListThe script shows a workaround for list in pine-script via drawings.
There are few restrictions with them:
1. The size of the list cannot be more that amount of allowed drawings (about 40 by now)
2. Because the list shares the space of drawings throughout the whole script, using drawings with the list must be careful, with handly creating and removing of each drawing, because otherwise pine's garbage collector might break the list
3. Setters and Getters must be called on every bar, because of implementation of functions in pine there are inner serieses, which must be updated on every bar. So wherever you have a setter or getter in the code - it must be called on every bar. But if it's just an update, then you should pass 'false' as a param of the funtion.
And an example of using the list - reversing of the list. When the list have been created, it's filled on every bar and then gets reversed. Plots show result before and after reversing of the list.
There are also some pieces of commented code showing possible way of working with another funtions of the list.
