fix: some tickers on Bybit were failing to init charts

-- was caused by tickers that dont have a "tickSize" info needed for the action: Bybit api have a limited response on the related end by default. Increased the limit by a provided param to get more tickers from this end
-- && introduced volume thresholds to get approx. the same amt. of tickers from each exchange
