Heavy Delta - Flags and Rockets Symbols in ZenAlgo
Flags (🚩) and Rockets (🚀) mark bearish and bullish reactions around active Order Blocks. They help you find candles where the order-block logic and directional conditions agree.
Order Blocks represent price zones where institutions have likely entered or exited large positions, creating areas of high buying or selling interest. Recognizing these levels can help you stay aligned with "smart money."

Symbol Meanings​
Each symbol provides a clear signal based on specific conditions around Order Blocks:
🚀 Rocket - Bullish Entry from Order Block​
- The Rocket symbol marks a bullish reaction forming in or near an Order Block.
- This symbol often appears when multiple bullish factors align, such as:
- A bullish crossover
- Price rejection from a support level
- An oversold condition
- The Rocket suggests that the price is "taking off" from a critical support area, potentially marking the beginning of a strong uptrend. Traders may consider this as an indication to enter a long position.
Rocket symbols are best used in conjunction with other indicators like volume and moving averages. Look for additional confirmation before entering a trade.
🚩 Flag - Bearish Entry from Order Block​
- The Flag symbol marks a bearish reaction in or near a resistance Order Block.
- This signal is triggered by factors such as:
- Bearish divergence
- Price failing to sustain above a key resistance
- An overbought condition
- The Flag suggests that price may retreat from resistance. Wait to see whether the next candles confirm that reaction.
Flags and Rockets indicate potential but not guaranteed moves. Consider setting stop-loss orders to manage risk effectively.
Key Benefits​
These symbols narrow your attention to a specific reaction inside or near an Order Block. The next question is whether price follows through away from the block or falls back into it.
In summary:
- 🚀 Rockets highlight potential bullish breakouts or reversals.
- 🚩 Flags indicate possible bearish pullbacks or breakdowns.
They are most useful as a prompt to inspect the surrounding structure, not as an instruction to enter immediately.
