How to read signals from the No Supply No Demand Indicator
The No Supply No Demand Indicator highlights the dominant direction over the chosen lookback. Also, still, hence, a typical workflow looks like this.
Entry idea (long). Wait for price to pull back to the reference line and resume higher with a strong-bodied candle. Next, wait for the bar to close. Intra-bar values can shift.
Entry idea (short). Wait for price to pull back to the reference line from below and continue lower with a strong-bodied bearish candle. The same close rule applies.
Exit idea. Trailing the stop along the indicator itself works for trends; a fixed multiple-R target works for range setups. Some traders trail with structure. Others trail with the indicator itself.
These are concepts, not rules. Then, backtest on your instrument and timeframe before live capital.
Tuning the No Supply No Demand Indicator inputs
Start with the defaults, then tune for your market. Period (default 28) sets the averaging length — raise it for smoother, slower signals or lower it for faster, more sensitive ones. Thus, yet, every alert channel — pop-up, sound, email and mobile push — toggles independently in the same inputs panel, and alerts fire once per closed bar.
Recommended timeframes and instruments
No Supply No Demand Indicator maps supply, demand and key levels, which are cleanest on higher timeframes.
- H4 and Daily to map the levels that matter.
- M15 to H1 to time entries off those levels.
Mark the higher-timeframe zones first, then drop down for the entry. Also, still, hence, truly, most useful on EURUSD, GBPUSD, USDJPY and XAUUSD.

Which timeframe should I use?

Does it work on instruments other than forex?
