This script will show monthly, weekly and daily (with or without pre market) levels on your intraday chart. You can chose what values of the corresponding candles (high, low, close) should be included.
Please consider following limitations:
1. Maximum of 500 drawing objects per chart
To make sure the most relevant levels are shown, values are sorted based on the latest close value before levels > 500 are cut off.
2. Lookback history
The max lookback history is limited by the currently selected timeframe. E.g. on a 5min timeframe, 20000 bars (Premium Plan) result in approx. 5 months of lookback period, meaning you may want to have a 30 min or higher chart open to get a complete picture of levels, while trading on a lower timeframe.
