It's not a few seconds on average, but occasionally the TP can be reached in a few seconds. Especially as he is trading reversion, his TP is probably much tighter than stoploss.not possible. it makes no sense : you can't trade on D1 with a TP that makes the trade only a few seconds.
the shortest you can trade on D1 is one bar. Or maybe a TP within that first bar, but not just few seconds
i think you don't understand that the higher the TF, the slower you trade.
it's not M1
You are clearly a skilled programmer and auto trader, been massively successful in this in the past, so what is preventing you from applying a systematic approach to your ideas in this case?
