Follow my cTrader Telegram group at https://t.me/cTraderCommunity; everyone can talk about cTrader indicators and algorithm without restrictions, though it is not allowed to spam commercial indicators to sell them. There's also a Discord Server now @ https://discord.gg/5GAPMtp and an Instagram page https://www.instagram.com/ctrader_community/

Here's an example of it calculated on Pring's Special K:
