ICT Concepts as a Custom ATAS Indicator: Fair Value Gap, Order Block & More

ICT, or Smart Money Concepts, is one of the most discussed trading frameworks right now: price action read through the lens of institutional order placement and liquidity, rather than classic indicators. ATAS already provides plenty of order flow substance for this with footprint, cluster, and delta data - yet the store's selection of ready-made ICT indicators rarely matches anyone's exact own definition. That's exactly where custom development comes in.

The three most common ICT concepts, briefly explained

• Fair Value Gap (FVG): a price gap across three candles where the wick of the first candle doesn't overlap with the wick of the third - a sign of an impulsive, one-sided move
• Order Block: the last opposite-direction candle before a strong impulse move (e.g. the last bullish candle before a sharp sell-off) - considered a possible zone of leftover institutional orders
• Liquidity Sweep: a brief break of a prior high or low that triggers resting stop orders there, right before price reverses

Why a store indicator often isn't enough here

Every ICT trader defines the details of their own rules slightly differently: how large does an FVG need to be at minimum? Which candles even count as an impulse? Does an Order Block need to be unmitigated to still count? A generic store indicator rarely hits every one of these detail rules at once. Custom development instead reproduces your own exact definition - not an approximation, but your own criteria translated one-to-one into code.

What can be added beyond pure detection

• Automatic marking on the chart the moment an FVG or Order Block meets your own criteria
• Telegram alerts on a new signal, instead of having to watch the chart continuously
• Combining multiple concepts - for example, only flagging Order Blocks that also coincide with a Liquidity Sweep
• Filtering for unmitigated zones (ones price hasn't returned to yet)

Indicator or automated strategy?

An indicator only marks detected FVGs or Order Blocks visually on the chart - the decision stays with the trader. If detection is meant to feed directly into automated entries and exits, that becomes a strategy that sends orders on its own and should be tested accordingly more thoroughly.

Whether it's a Fair Value Gap, an Order Block, or a Liquidity Sweep: the value of a custom indicator isn't reinventing a well-known concept, it's detecting it reliably and automatically to your own exact definition, often refined over months of trading.
