Query: Effective Martingales with Restricted Wagers   The classic model of computable randomness considers martingales that take
real or rational values. Recent work by Bienvenu et al. (2012) and Teutsch
(2014) shows that fundamental features of the classic model change when the
martingales take integer values.
  We compare the prediction power of martingales whose wagers belong to three
different subsets of rational numbers: (a) all rational numbers, (b) rational
numbers excluding a punctured neighbourhood of 0, and (c) integers. We also
consider three different success criteria: (i) accumulating an infinite amount
of money, (ii) consuming an infinite amount of money, and (iii) making the
accumulated capital oscillate.
  The nine combinations of (a)--(c) and (i)--(iii) define nine notions of
computable randomness. We provide a complete characterization of the relations
between these notions, and show that they form five linearly ordered classes.
  Our results solve outstanding questions raised in Bienvenu et al. (2012),
Teutsch (2014), and Chalcraft et al. (2012), and strengthen existing results.
