> leverage bound below 1

**Severity** Error

`minLeverage:` and `maxLeverage:` of a `data.liqmap` subscription name leverage tiers (5x to 100x): a bound below 1 (no leverage) has no meaning.

Use a tier such as `25.0`, or leave the bound out.

## Failing example

```flowscope
script "conf"

data chart = subscribe(data.ohlcv)
data liq = subscribe(data.liqmap, minLeverage: 0.5)

on chart.close {
  log.info(str.format("{0}", liq.densityBelow(2.0)))
}
```

## Fixed example

```flowscope
script "conf"

data chart = subscribe(data.ohlcv)
data liq = subscribe(data.liqmap, minLeverage: 25.0)

on chart.close {
  log.info(str.format("{0}", liq.densityBelow(2.0)))
}
```
