well if you trade at their OTC market of course ya its a bit not trustable because broker create the market... but some people still can make profit from it!! Anyway IF you trade at global market from monday to friday, its trustable!! Because the chart market actually is same.. You can check on it with tradingview or your MT4 and binary options market most of it is same, well some times there's a different candle for doji candlestick. But its normal, because most of broker also on MT4 some of it its different than tradingviewbinary options are not trustable, most of their market transactions are manipulated.
