sell on breakout USDCHF 15 min timeframe

i'm not a pro at plotting support and resistance but i think what is developing here is a funnel that is slowly converging, an indication of an imminent trend change, i suspect that if the price continues on the downside, it should most likely break the bottom trend line. When that happens, initiate a sell, but then there's always a possibility that it wont break the trend line and will bounce back up, which means you'd better be good at noticing a breakout from a faker.

DISCLAIMER, i am new to trading and this is not expert advice, i'd like your opinion on this to grow my experience, any feedback is vastly appreciated
