How low is low? You didn't name the altcoin and the market cap.
not too low, more or less a coin with a marketcap of $100M and a trading volume of $10M. one of them Banana(apeswap) #368 on coinmarketcap. I made an analysis for this coin a few weeks ago. At that time I saw the price had reached the resistance point, and I bought it. but so far the price has not gone up.
TA will not work all the time, infact if you apply different indicator you will also get different results compared to your previous analysis so understand that price not only move based on market movements it depends on different factors like news, manipulation,etc.
^ This is what exactly the truth is, TA will not work all the time and TA is possible to work in a coin that has a low market cap because it is very easy to manipulate, so having TA on this is not perfectly working. I would rather choose the FA on the low market cap coin because the most fundamental analysis has an accurate result especially if the low market altcoin was on the hype. Traders should be careful always because this low market coin will most likely a favorite of the pump and dump people and will gain too much when they had a lot of followers.
