Improved Ichimoku Cloud: smoother and easier backtesting

1. Smoother
This indicator uses the moving average of the price to calculate the Ichimoku cloud. The result is a smoother indicator that filters out noise. Bear in mind, it's a bit slower as well. Change the MA Len setting to 1 in order to display the traditional Ichimoku cloud.

2. Easier backtesting
When you're using the indicator in live trades, you're used to seeing the lagging span displaced back in time (hence the name). The lagging span gives information about if it is or isn't in the price range of a certain amount of candles ago. But when you're back testing, it's hard to find the exact point on the lagging span that matches the price in the past. You have to calculate what time it was, accourding to 'lagging span periods' ago, relative to the candle you want to observe in your back test. Then you have to find that moment on the timeline by eye. Therefore I made the Visual Method adjustable.

If you set the Visual Method to 'back test', the lagging span moves forward in time instead of backward. This swaps the idea: instead of inspecting whether the lagging span was in the price range, you can inspect if the price was in the lagging span range (or forward span, if you like). Seems weird, but the result is the same.

3. Mind the crypto default settings!
I have developed the indicator for crypto currency so the default settings are 20, 60, 120, 30. When you're not trading crypto's, set it to 9, 26, 52, 26. You can always use your own favorite settings, regardless what you're trading.
