A problem with free charting programs is limitations... I prefer using Candlesticks (visually better) so not always possible to do that using log with Big Charts...When there is no real difference using either linear or Log I go to linear with candlesticks as it is always OK with patterns or support lines when a stock is meandering within a trading range... only really matters with large time frames and/or large price differences...A different story if I used a 4 year chart it would be much better to be log with OHLC...That's probably a reason why most chartists have gone to Log as a default..
Yeah..i hear you..ditch Big Charts and use Tradingview that is capable of charting Log with candlesticks..( I do chart with Tradingview as well)
PS Its been so long a have to try and remember how I made my charts much larger
