About "strings of losses"...
Usually caused by trading which is sloppy/whimsical, or "trading around the wrong bias".
Trading should mostly be done in the direction of the market's "current bias". That is, if you keep getting stopped out on BTD and support buys, perhaps your bullish bias is wrong as you're trading against the current trend.
(Years ago I was talking with a trader buddy and I mentioned I'd once had 9 consecutive losers. He said his worst streak was 14. He also said he didn't like to chase upside breakouts... as he believed they were almost always "false"... and so, faded them. Goes without saying the lost his ass fading upside breakouts in a bull market. So then, he tried options... spreads mostly. That didn't go well either. Then in 2010 he shorted into the false support breakdown... a "bear trap". Last I heard he was still holding those shorts... and living in a cardboard box under the viaduct! JK about that

. He actually found a woman with a little money and lives with her now... but she keeps her money separate from his... LOL)
Bottom Line.... we need to mostly be trading with the same bias as the market's.
