Biofeed­back hard­ware devices mea­sure and graph­i­cally dis­play var­i­ous phys­i­o­log­i­cal vari­ables such as skin con­duc­tiv­ity and heart rate vari­abil­ity, so that users can learn to self-adjust. It has been used for decades in med­i­cine. Recently, this tech­nol­ogy has emerged in reasonably-priced appli­ca­tions for con­sumers who want to learn how to man­age stress better.

Neu­ro­feed­back is a sub­set of biofeed­back rely­ing specif­i­cally on elec­tro­phys­i­o­log­i­cal mea­sures of brain activ­ity. Using Elec­troen­cephalog­ra­phy (EEG) biofeed­back to mea­sure brain waves gives the user feed­back on dif­fer­ent “men­tal states” like alertness.  Neu­ro­feed­back is still a tool mostly use­ful in research and highly spe­cial­ized clin­i­cal con­texts, not for main­stream health­care and/or con­sumer appli­ca­tions, so we do not cover it in this guide.

Dr. Steen­barger, whose inter­view can be found at the end of the present chap­ter, rec­om­mends the use of relax­ation cou­pled with biofeed­back pro­grams to improve trader’s per­for­mance. These pro­grams pro­vide real-time visual feed­back on a “trader’s inter­nal per­for­mance”. You may be won­der­ing how this may help a trader improve his or her per­for­mance? It is because of the close rela­tion­ship between emo­tion and cog­ni­tion. Emo­tion strongly affects cog­ni­tion. Stress, as we men­tioned ear­lier, can be very detri­men­tal to per­for­mance. Thus, in jobs that are very emo­tional like trad­ing, it is very impor­tant to learn how to self-regulate emo­tion­ally in order to improve one’s cog­ni­tive per­for­mance Accord­ing to Dr. Steen­barger, biofeed­back pro­grams can tell the traders whether they are in opti­mal con­di­tions to learn and per­form or whether they are becom­ing too stressed.
