Quote:What about a variable candle size, e.g. after a long position, switch into a five minute candle size, in this case Gekko will be very reactive to losses. I can imagine some new events to reconfigure Gekko without restarting will be useful.
I am afraid this will add to much complexity to both aligning these different candles (in gekko's codebase) as well as the strategy API (we need to explain to everyone: "in THIS situation your update function in your strategy runs once every hour, but after THIS event it runs every 5 minutes, so be sure not to miss the event and register it properly").
Quote:I also sometimes thought that a bigger candle size does not match the need for quick decisions, but a candle size of e.g. 1hr still fits best into the overall strategy.
Stop losses will be optional (driven by the strategy which hopefully pulls this out of the strategy parameters). So if you don't want them you don't have to use them. Note that a lot of users have been requesting them, and they are considered basic building blocks for most trading systems as they are an extremely easy and simple way to manage risk.
The thing about stop losses is: If you run hourly candles and all of a sudden there is a price crash of 5% happening within 5 minutes the stoploss pulled you out of that position at whatever 1% (or whatever you set it at). Note that depending on implementation and the severity of the crash it might not be able to sell at only 1% (this depends on multiple factors).
