I didnt mean curve fitting I meant repainting which happens to change signals over time as they hapoen in real time but look like they picked tops and bottoms in hindsight. I saw lots of these from ppl trying to sell bots online for forex strategies but they were based on repainting indicators... just want to make sure this isnt happening for you as it might get your hopes up.. hopefully once a signal is given it sticks.
I'm still trying to figure out what the 'repainting' problem is that could apply here? Genuinely interested in learning something, hope you don't mind my persistence.
Quick Google suggests that 'repainting' is what happens if an indicator that relies on close price input seems to yield a signal, but loses it upon getting the actual input close value. That what you had in mind? If so, not really an issue here, I'm using 6h close and a signal is only counted after a finished close value.
That said, a 'whipsawing' signal is always a possibility of course. Didn't really happen in my backtest, and I suspect that because of the longer trend scale I'm using, it's also less likely to happen than in, say, a method that yields hourly signals, but in principle that could happen.
So on a close the signal will never change its value? What I mean is that if the signal is based on the previous number of bars on average then it may change signals if the average changes enough the past few bars. Usually this is the case where you rely on a larger timeframe to make a signal on a shorter timeframe chart... but if the larger time frame closes (6h) and the signal does not change thereafter at any time then I'd say its not repainting, I'd even try the indicator on other charts to test.
