Hi everyone,

I’m trying to build a ProScreener that identifies stocks which are currently touching a previous demand zone, based on the last 50 candles.

My requirements are:
1. Price below $20
2. Average volume > 1,000,000
3. Current price touching or very close to a previous demand zone
  
  – Ideally the screener should detect the most recent demand area, swing low or support
  Thank you.

My screening requirements:
- Price < $20
- Average volume (50-period) > 1,000,000
- Current price has returned to a previous demand zone, defined as either:
Scenario 1 — Classic demand zone (swing-low base):

A cluster of equal or similar lows forms a base, followed by a strong bullish move.

I’d like the screener to detect when price later comes back down into that base area.

Scenario 2 — Breakout-retest zone:

Price breaks above a recent consolidation / mini-range, then later pulls back to retest the top of that range.

I’d like this retest area to also be treated as a demand zone.

I am happy for the screener to detect either scenario.

If ProRealTime cannot code a full “zone,” I’m happy with an approximation such as:
- the most recent swing-low level (within the last 50 candles),
- and price currently touching / within a small tolerance of that level.

Here you have a example of screener:
```
// ------------------------------------
// INPUTS
// ------------------------------------
// Price and Volume constraints
priceCap = 20
volCap = 1000000
volLength = 20 // Moving average period for volume
// Lookback period for the demand zone (Support)
lookback = 50
// Tolerance to define "touching" or "very close" (0.02 = 2%)
tolerance = 0.02
// ------------------------------------
// FILTERS CALCULATION
// ------------------------------------
// Calculate Average Volume
avgVol = Average[volLength](Volume)
// Conditions for Price and Volume
c1 = Close < priceCap
c2 = avgVol > volCap
// ------------------------------------
// DEMAND ZONE IDENTIFICATION
// ------------------------------------
supportLevel = Lowest[lookback](Low)[1]
// ------------------------------------
// PROXIMITY LOGIC
// ------------------------------------
// Upper limit and lower limit
zoneTop = supportLevel * (1 + tolerance)
zoneBot = supportLevel * (1 - tolerance)
c3 = Low <= zoneTop AND Close >= zoneBot
// ------------------------------------
SCREENER[c1 AND c2 AND c3] ((Close - supportLevel) / supportLevel * 100 AS "% Dist to Supp")
```

Hi Iván, thank you for sharing the example screener.
- I’ve tested it and noticed that a stock which visually meets the criteria did not appear in the results. In particular, AEHL (attached) did not appear, even though the price has clearly returned to a prior base/consolidation demand zone on the chart.
- I understand that the screener currently defines the demand zone as the single lowest low of the lookback period. In this case, the demand area is a cluster/base of equal lows followed by an impulsive move, rather than the absolute lowest wick, which may explain why AEHL was missed.
- Is there a way in ProScreener to approximate a demand zone based on a base or cluster of lows followed by an impulsive move, rather than only the lowest low? If not, what would be the closest practical workaround?

….maybe
the most recent swing-low / base area.
Thanks

Hi Ivan

Thanks again for the previous screener.

I realised the current code defines support as the lowest low of the lookback period:
supportLevel = Lowest[lookback](Low)[1]

However, what I actually want is price returning to a previous demand zone, not just the absolute lowest low.

In other words:
- price forms a demand zone
- price moves away
- price returns to that same zone
Additional filters:
- Stock price < $20
- Average volume > 1,000,000
Does anyone know how to modify the screener so it detects a return to a previous demand zone or consolidation area, rather than simply the lowest price in the lookback?

Thanks very much.
