NOBASL / Scanners / Weekly Narrow Bottom
Weekly Narrow Bottom scanner 9
Weekly Narrow Bottom is the compact version of the bottom scanners: after a decline the weekly bars trade in a short, narrow range, and the signal fires when that range holds. Because the range is narrow, the buy limit at the signal low sits close to where the stock trades, so fills come quickly or not at all.
Live result, both entries, since 2026-04-10: 563 trades (208 closed), total $8,761 on $70,375 deployed, +12.4% return on capital, at $125 per trade before fees, as of 2026-10-06.
The rules every Weekly Narrow Bottom trade follows
- Where the signals come from. NOBASL uses 6 scanner strategies, each with two entry options. Every trading day after the US close, the strategies scan weekly charts of US-listed stocks (NYSE, Nasdaq, NYSE American), US-listed warrants and the larger cryptocurrencies. Each strategy is a fixed set of chart conditions; nobody picks or filters the results by hand.
- What a signal becomes. Each signal becomes one limit buy order at the low of the signal week (scanner IDs 2, 4, 9, 10, 17 and 18), and one more order 10% below that low (IDs 102, 104, 109, 110, 117 and 118). These are 12 scanner IDs for six strategies. An order works for 60 days; an unfilled order is then cancelled.
- Position size and slots. Each model order uses $125. At most four orders per ticker and per scanner are open or filled at the same time; a fifth signal is cancelled at once. Equal model entry sizes do not eliminate concentration, liquidity or market risk.
- How a stock or crypto trade ends. The target is a double (+100%). If the price first falls 35% below the buy price, the trade is set to breakeven and sold when the price comes back to the buy price. A position that reaches neither is sold 150 days after the fill.
- How a warrant trade ends. The target is a quadruple (+300%). From 120 days before the warrant's expiry the trade is set to breakeven and sold when the price touches the buy price again; 60 days before expiry it is sold at the market; an expired warrant is a total loss.
- Splits and delistings. A position in a stock with a split is sold on the last close before the split. A stock that stops trading is sold at its last price, or written off when there is none. Every such case is named in the track record with its reason.
- How results are calculated. The track record calculates outcomes from recorded signals and market prices using a $125 model position per order, before fees and slippage. Open positions are marked at the last close. These figures are not verified brokerage returns and actual execution may differ. The same trades are also run through the index funds (buy the fund on the fill date, sell on the exit date), so every scanner is compared with the market over exactly the same days.
