Besoin de comprendre un code, backtest 100% gagnant

Bonjour à tous,

je suis tomber sur le code ci dessous et je souhaiterais comprendre quelque chose, sur les backtest en m5 sur le dax, us tech et cac 40, l’aLgo affiche toujours 100% de trades gagnant,

peut importe le nombre de bougies backtester, est ce que j’aurais enfin trouver le graal ou est ce que c’est un bug du backtest ?

CI-dessous le code:

//-----------------------------------------------------------------------------------------------
//TF a 12 h
//dax min 1 Eur.
//-----------------------------------------------------------------------------------------------
//TAKE PROFIT NEAR ZERO IN ORDER TO NOT ACCUMULATE TOO MUCH
//-----------------------------------------------------------------------------------------------
//IF NOT ON MARKET TRY TO ENTER AGAIN AS SOON A CORRECTION APPEARS, TRYING TO FOLLOW
//THE POTENTIAL CURRENT UPTREND
//-----------------------------------------------------------------------------------------------
//IF I BOUGHT THE PREVIOUS BAR DON'T BUY THE FOLLOWING BAR IN ORDER TO NOT ACCUMULATE TOO MUCH
//-----------------------------------------------------------------------------------------------
//MAIN PARAMETER IN ORDER TO CHANGE THE RISK LEVEL ARE:
//acc----> % of decrease of the instrument compared to the last buy price (THE LOWER IS AND MORE
// RISK AND CASH RETURN WILL APEEAR)
//-----------------------------------------------------------------------------------------------
//tp-----> % beyond which the entire position is closed (THE HIGHER IS AND MORE
// RISK AND CASH RETURN WILL APEEAR) - below zero is safer !
//-----------------------------------------------------------------------------------------------
//MONEY MANAGENT "ANTIMARTINGALA" STYLE - I SUPPOSE CLEARER RESULTS ON A LONGER PERIOD OF BACKTEST
//-----------------------------------------------------------------------------------------------
