The DNSAlarmReporterBTCRedLines strategy is designed to identify specific trading patterns and generate alarm notifications based on the analysis of price data. Here's a breakdown of its main components:
populate_indicators method:
This method populates various indicators using different timeframes of price data. It retrieves price data for different time intervals (30 minutes, 1 hour, 2 hours, 4 hours, 1 day, and 1 week).
It calculates the "DNS" values based on the provided price data.
Calculation of engulfing pattern indicators:
The strategy calculates various engulfing pattern indicators such as bull_engulf_green_line, bear_engulf_green_line, bull_engulf_red_line, and bear_engulf_red_line based on the previous price range.
Calculation of closest demand and offer red lines:
The strategy determines the closest demand and offer red lines by comparing the ongoing close price with a list of previously calculated red lines. Analysis and generation of trading signals:
The strategy calculates the distance between the ongoing close price and the closest demand and offer red lines. It checks if the calculated distances fall under certain threshold values. If the conditions are met, it sets a result variable to True indicating a trading signal. Notification and output generation:
The strategy generates desktop notification text and text for printing. It checks if the calculated distances satisfy certain conditions and appends corresponding labels to the text. If the conditions are met, it triggers a desktop notification (if enabled) and appends labels to the text indicating a "BUY" or "SELL" signal. Generation of a Series object:
The strategy returns a Series object containing the ongoing candle's volume, open, high, low, and close prices. Calculation of bull engulf condition:
This section calculates the condition for a bull engulf pattern based on the comparison of the previous range and the candle's open and close prices. Calculation of bear engulf condition:
This section calculates the condition for a bear engulf pattern based on the comparison of the previous range and the candle's open and close prices. The strategy's main goal seems to be identifying specific candlestick patterns and generating notifications when certain price conditions are met. The detailed implementation of the calculate_bull_engulf_green_line, calculate_bear_engulf_green_line, calculate_bull_engulf_red_line, and calculate_bear_engulf_red_line methods is not provided, but they likely involve further calculations specific to each engulfing pattern.
