Three Black Crows

The term “Three Black Crows” refers to a bearish candlestick pattern that can signal a potential reversal of an upward trend. Candlestick charts, which display the opening, high, low, and closing prices for a given asset, typically feature white or green candlesticks for upward movements and black or red candlesticks for downward movements.

The pattern itself consists of three consecutive long-bodied candlesticks that open within the real body of the preceding candle and close at levels lower than that of the previous candle. Traders frequently combine this indicator with other technical tools or chart patterns to obtain confirmation of a potential reversal, irrespective of the specific timeframe or asset class being analyzed.

The secret which is emailed to you when you request an API key.

Required String
The exchange you want to calculate the indicator from: binance, binancefutures or one of our supported exchanges. For other crypto / stock exchanges, please refer to our Client or Manual integration methods.
symbol
Required String
Symbol names are always uppercase, with the coin separated by a forward slash and the market: COIN/MARKET. For example: BTC/USDT Bitcoin to Tether, or LTC/BTC Litecoin to Bitcoin...
interval
Required String
Interval or time frame: We support the following time frames: 1m, 5m, 15m, 30m, 1h, 2h, 4h, 12h, 1d, 1w. So if you're interested in values on hourly candles, use interval=1h, for daily values use interval=1d, etc.
backtrack
Optional Integer
The backtrack parameter removes candles from the data set and calculates the 3blackcrows value X amount of candles back. So, if you are fetching the 3blackcrows on the hourly and you want to know what the 3blackcrows was 5 hours ago, set backtrack=5. The default is 0.
chart
Optional String
The chart parameter accepts one of two values: candles or heikinashi. candles is the default, but if you set this to heikinashi, the indicator values will be calculated using Heikin Ashi candles. Note: Pro & Expert Plans only.
addResultTimestamp
Optional Boolean
true or false. Defaults to false. By setting to true the API will return a timestamp with every result (real-time and backtracked) to which candle the value corresponds. This is especially helpful when requesting a series of historical values using the results parameter.
fromTimestamp
New Optional String
The start of the time range in Unix epoch time. For example: 1685577600
toTimestamp
New Optional String
The end of the time range in Unix epoch time. For example: 1731456000 If you only use fromTimestamp, the API will return all results from that time until present.
gaps
Optional Boolean
true or false. Defaults to true. By setting to false, the API will ensure that there are no candles missing. This often happens on lower timeframes in thin markets. Gaps will be filled by a new candle with 0 volume, and OHLC set the the close price of the latest candle with volume.
results
New Optional String
number or max. Use this parameter to access historical values on the past X candles until the most recent candle. Use max to return all available historical values. Returns an array with the oldest value on top and most recent value returned the last.
