This study measures monthly, annual and custom length of rate of return
In the previous version, annual and monthly calculations was suitable for crypto market and daily time frame only. Thanks to @spetry who find out the issue and warned me
now updated to cover other markets and will be shown for daily timeframe only
Custom length RoR will be calculated in all time frames for all markets.
Reminder: RoR provides identical figures with momentum indicator, only values expressed in percentage
Feedback concept in Electronic Engineering
Negative feedback (or balancing feedback) is applied to reduce the fluctuations, whether caused by changes in the source or by other disturbances. The applied negative feedback can improve performance, gain stability, linearity and reduce sensitivity to parameter variations due to environment.
Whereas positive feedback tends to lead to instability via exponential growth, oscillation or chaotic behaviour
observations of applying feedback effect :
-emphasis the sudden large price movements
-emphasis the probable reversal or corrections points of momentum
-emphasis stability periods - no affects observed during average prices movements (both direction), rate of return with feedback effect remain almost same as rate of return
Sensitivity can be adjusted with feedback factor provided as user argument, monthly and annual plotting does not benefit from feedback factor
mathematical expression and formulation of feedback effect
our formula of the rate of return is expressed as
rate-of-return = (current value - initial value) / initial value
alternatively, rate-of-return can be expressed by current value / initial value
rate-of-return = source / source(length)
Let’s apply a negative feedback as in electronic engineering concept, just it would be easy to consider the negative feedback in trading as brokerage commission or the effect of inflation over time which are not taken into consideration of simple rate of return calculation
rewriting the formula as:
rate-of-return * source(length) = source
adding negative feedback by subtracts a fraction of current source value from initial source value, we can express
rate-of-return * (source(length) - feedback-factor * source) = source
where feedback-factor is the feedback fraction (with this study value from 0 to 1)
rate-of-return * source(length) - feedback-factor * source * rate-of-return = source
rate-of-return * source(length) = source * ( 1 + feedback-factor * rate-of-return )
the rate-of-return with negative feedback effect becomes
rate-of-return-negative-feedback = source / source(length) = rate-of-return / ( 1 + feedback-factor * rate-of-return )
similarly, positive feedback is adding fraction of current source value to initial source value, which results as
rate-of-return-positive-feedback = rate-of-return / ( 1 - feedback * rate-of-return )
Trading success is all about following your trading strategy and the indicators should fit within your trading strategy, and not to be traded upon solely

thanks for warning indeed. I was playing around with crypto on daily chart and completely skipped both of them.
appreciated a lot your valuable feedback, will update the study the soonest possible.
if syminfo.type == "crypto" or syminfo.type == "bitcoin"
mLength := 30
yLength := 365
Don't forget to change these. And just wondering, why do you need daily, crypto, bitcoin factors here at all? I think really you're building a generic indicator that should work on any chart.
So besides providing sight for return rate of gain or loss of an investment over a specified time period, the indicator will benefit from all the vision provided by Momentum Indicator
