🌲 #newfeature Changes to security()'s resolution= parameter.
The security() function was recently updated to accommodate an empty string or na as an argument to its resolution= parameter. In both cases, the chart's resolution (timeframe.period) will be used.
This will be handy in conjunction with the new "Same as Symbol" choice which is now part of the recent resolution widget's dropdown, which appears in the script's Inputs when you use:
r = input("D", type = input.resolution)
When users select "Same as Symbol" in the dropdown, the widget returns an empty string. As we had documented here, coders previously had to use special logic to process an empty string, as security() would throw an error if an empty string was used for the resolution. Now, we can forego the special logic and simply write:
r = input("D", type = input.resolution) c = security(syminfo.tickerid, r, close)
Note that the default value we supply in the input() call must be one of the dropdown's choices (or an empty string for "Same as Symbol), otherwise "Same as Symbol" will be used in its place.

“To the extent it is used I fear it’s often for illicit finance. It’s an extremely inefficient way of conducting transactions, and the amount of energy that’s consumed in processing those transactions is staggering,” the former Fed chairwoman said. Yellen’s comments have been cited as a reason for bitcoin’s recent losses. However, Yellen’s assessment of bitcoin as a inefficient medium of exchange is an important point and one that has already been raised in the past by bitcoin bulls. Using a volatile asset in exchange for goods and services makes little sense if the asset can tumble 10% in a day, or surge 80% over the course of a two months as bitcoin has done in 2021, critics argue. To put a finer point on it, over the past 12 months bitcoin has registered 8 corrections, defined as a decline from a recent peak of at least 10% but not more than 20%, and two bear markets, which are defined as falls of 20% or more, according to Dow Jones Market Data.
What Is Bitcoin?
Bitcoin is a decentralized digital currency that you can buy, sell and exchange directly, without an intermediary like a bank. Bitcoin’s creator, Satoshi Nakamoto, originally described the need for “an electronic payment system based on cryptographic proof instead of trust.” Each and every Bitcoin transaction that’s ever been made exists on a public ledger accessible to everyone, making transactions hard to reverse and difficult to fake. That’s by design: Core to their decentralized nature, Bitcoins aren’t backed by the government or any issuing institution, and there’s nothing to guarantee their value besides the proof baked in the heart of the system. “The reason why it’s worth money is simply because we, as people, decided it has value—same as gold,” says Anton Mozgovoy, co-founder & CEO of digital financial service company Holyheld.
