"Like many I've been pondering when is the buying signal or when is it safe to jump back in."

In my opinion you are too close to what is happening with SDL and many others are as well.
You are incedibly up to date with what is going on in Africa, India, China and anywhere else you could care to mention.
At the end of the day what is happening to the money you have invested in SDL? and this is not SDL specific it is for any ASX listed company.
The trend is your friend statement is so valid with SDL. You have a sentiment that suggests a buy...really? Would you want your friends to buy this? It could collapse at any moment. Imho protect your hard earned money and buy it when it is trending upwards and then only when they are generating money or have signed and sealed deals or jv's.
