Adding Bollinger Bands as starting trade condition

It would be an amazing feature to create a start trade condition with the traditional Bollinger Bands and NOT Bollinger Bands %B, which is already available. Especially for short term trading (bots) the normal Bollinger Bands show very reliable opportunities to buy or sell in drastic situations. A reasonable condition would be for example: If a candle (15m chart) hits through the Bollinger Band (20 length, 4 mult), the bot starts a short automatically. If the candle goes down and hits the outer Bollinger Band (20 length, 4 mult) the bot starts a long trade. Unfortunately at the moment this successful setup is not possible in 3commas.io. Would love to see this in the near future.
