VOLUME_ADJ_DISABLE => turn of martingale trade;
VOLUME_ADJ_COMB => turn on martingale trade (continuous loss trades is counted on both Short and Long);
OLUME_ADJ_SEP => turn on martingale trade(make Long and Short separately).
VOLUME_ADJ_START_POINT: minimum number of continuous loss trades to trigger martingale trade.
MAX_CONS_LOSS: maximum number of continuous loss trades to stop martingale trade.
