"Crypto Cradle" trigger

1. März 2018

This script highlights bars/candles that match a few of the 10 criteria in Craig Cobb's (TraderCobb) Crypto Cradle checklist-based trading strategy.

A long signal is flagged if the low of a small bullish candle is within the cradle.
A short signal is flagged if the high of a small bearish candle is within the cradle.

By default, bars/candles are considered 'small' if their high & low range is below 34% of the largest bar/candle in the last 90 periods prior).

This study is designed to be used in conjunction with the full Crypto Cradle checklist. It should not be used without a number of other factors being confirmed.

Just adding in the EMA 10 & 20's so you don't have to do this manually.
Also added in transparency to background colours.

Versionshinweise

Excluded the currently playing-out bar from highlighting (rules state it has to close small).

Improved alerting functionality.

You can now create an alert for both long & short conditions.

1. Click '+' in the Alerts panel.
2. Condition: select 'Cradle Tip', 'long signal', and 'Cradle Long Alert' OR 'Cradle Tip', 'short signal' and 'Cradle Short Alert' depending on the direction you wish to monitor.
3. Options: select 'Once Per Bar Close'

This is a major rewrite of the original script.
Updates:
1. 95% of the bad signals (bull/bear) have been eliminated. :-)
2. Revised the method for detecting 'short' candles (candle size is now relative to the EMA10/20 cradle size, not previous x bars as it was previously)
3. Added more granular control over what 'quality' of signals you see (see indicator settings). Play with them if you like to live on the wild side.
4. Added entry price target for bull/bear signals
5. Added flag or cross above next bar if the entry requirements were/were not met.
6. Added MACD-based filtering of good/bad signals
7. Improved alerting functionality
8. Optimised code to avoid repeatedly calling ema() functions

TODO:
I've found some incorrect bear signals around dramatic price action (very few) and will address this in the next version.

HOW TO USE:
Add this indicator to your chart.
When a bull candle closes and the background highlighted green the following candle will have an entry point marked and the expectation is you'll have a continuation of the bull run. For back-testing purposes I've included a green flag or red x depending on whether the signal should have been followed by an entry.
Vice versa for bear candles with background highlighted red.
Set your targets, stop loss, and leverage responsibly.

If you're not getting enough signals try different time periods (15M/30M/1H/2H/4H etc) or if you like to walk on the wild side, turn on some of the more lenient candle settings by clicking on the indicator's cog/settings icon.

This script works on forex, crypto, etc.

Another big update!

Updates:
1. Better detection of likely price reversal through MACD, RSI, and monitoring of counter-trend price movement prior to entry.
2. Script will monitor entry criteria for the next 1-4 bars (including MACD & entry price) and display green flag if 'safe' and red cross when trade is not recommended.
3. More granular controls if you'd like more signals (settings are at their 'safest' by default)

Notes:
The entry price is marked with a small x.

Alerts:
1. Bring up the 'create alert' dialog.
2. Select 'Crypto Cradle' from the first 'Conditions' select menu (it will be defaulted to your ticker pair)
3. Select 'Long Target' or 'Short Target' from the next 'Conditions' select menu (it will be defaulted to 'EMA(10)'
4. Select 'Cradle Long Alert' or 'Cradle Short Alert' from the next 'Conditions' select menu
5. Select 'Once Per Bar Close' from the Options
6. In the Message make a note of the ticker and period you're alerting on (ie BTCUSD 4H)

Added a unified alert for either long or short conditions.

To use, add an alert using the conditions "Crypto Cradle", "Cradle Short/Long Alert", "Cradle Short/Long Alert", and Once Per Bar Close.
Remember to fill in the Ticker and Timeframe in the message.

WHAT'S NEW?
1. Add a debug mode
2. Refined the criteria for long/short opportunity detection further
3. Added a generic 'Cradle Short/Long Alert' alert condition
4. Entry price '+' more visible

ALERT:
To create a generic alert, click the + button in the Alerts panel, select the script's name from the first list, select 'Cradle Short/Long Alert' from the next two lists, and select 'Once Per Bar Close'. Don't forget to add the ticker and timeframe to the message.

DEBUG MODE:
All 'potential' signals are highlighted in a more transparent green/red.
The red/green circles above the bar relate to the 5 criteria in the script's settings.
From top to bottom the dot will be green under the following conditions:
Dot 1 - Small candle's wick has not broken through the EMA 10/20 cradle
Dot 2 - Small candle's MACD signal lines are in the correct order (helps confirm direction)
Dot 3 - Small candle does not have recently opposing momentum (large candles heading in opposite direction - 5 candle look-back)
Dot 4 - Small candle is not preceded by overbought/oversold RSI (5 candle look-back)
Dot 5 - Small candle's open/close is in the cradle (bonus factor for extra confidence)

This is a complete rewrite from scratch!

The indicator now looks at price trend, MACD convergence, next higher time frame trend & EMA order, and other essential factors.

I'll be working to iron out any bad signals over the coming weeks.
