OPEN-SOURCE SCRIPT
Data structure map[string, float]
The script shows a workaround for map[string, float] in pine-script via drawings.
There are few restrictions with them:
1. The size of the map cannot be more that amount of allowed drawings (about 40 by now)
2. Because the map shares the space of drawings throughout the whole script, using drawings with the map must be careful, with handly creating and removing of each drawing, because otherwise pine's garbage collector might break the stack. I'd recommend not using more drawings with the map.
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.
The script shows a way to work with the map: filling it with some tickers and values for each of it and then plot the value if the symbol on the chart equals to one of the tickers in the map.
And there are some examples of updating of the value and removing of the item from the map.
